- Abstract
Developmental education has the mission of enabling underprepared students to acquire the capabilities necessary for college success. A growing number of research studies document its failure, however; specifically, approximately two thirds of community college students referred to a remedial mathematics sequence do not complete it. In response to these findings, The Carnegie Foundation for the Advancement of Teaching, with the Charles A. Dana Center as a principal design partner, is launching a comprehensive initiative to create two new pathways, the Statway and the Mathway, to enable developmental mathematics students to complete a credit-bearing, transferable mathematics course in one academic year while simultaneously building skills for long-term college success. The primary curricular goal of the Statway course sequence is to develop the mathematical proficiency of students pursuing non-STEM academic and occupational programs, with a special focus on statistical literacy. This paper describes the research-based Statway design and its intended learning outcomes, the processes and participants involved in its development, and the challenges of implementation. Appended are: (1) Statway Collaboratory Colleges; (2) Mathway Collaboratory Colleges; and (3) Members of the Carnegie Committee for Statistics Learning Outcomes (CCSLO).

- Abstract
The National Centre for Vocational Education Research (NCVER) was asked by Technical and Further Education (TAFE) Directors Australia to consider, in a discussion paper for their conference held on the Gold Coast in September 2009, how a "tertiary education" sector impacts on the way people think about research and statistics. While a tertiary education focus would be a forward-looking step, it is important that both vocational education and training (VET) and higher education issues receive due attention. Individuals need to build on the good work done for the VET sector rather than subsume it in any sense. What is needed to make sense of the education, participation and achievement of individual students is an integrated tertiary education statistical system. This would require a common core set of standards. It would be relatively straightforward to populate a tertiary education student database from different collections. This database would then be a resource for policymakers and researchers. An integrated approach is required, not an approach which appends higher education statistics to the VET statistics or vice versa.

Das, Amaresh
- Abstract
This paper makes an econometric testing of one-minute paper used as a tool to manage and assess instruction in my statistics class. One of our findings is that the one minute paper when I have tested it by using an OLS estimate in a controlled Vs experimental design framework is found to statistically significant and effective in enhancing students' knowledge. It is found to be equally effective when I have tested it by using a seemingly unrelated regression that allows the error terms to be correlated across separate but related regressions. This is irrespective of students' ability levels as is measured by GPA in both cases.

Appalachian Collaborative Center for Learning, Assessment, and Instruction in Mathematics (ACCLAIM) and Showalter, Daniel A.
- Abstract
Place-based mathematics education (PBME) has the potential to engage students with the mathematics inherent in the local land, culture, and community. However, research has identified daunting barriers to this pedagogy, especially in abstract mathematics courses such as algebra and beyond. In this study, 15 graduates of a doctoral program in rural mathematics education were interviewed about their attempts to integrate PBME in their classrooms. By using qualitative methods to code and categorize interview data, three themes emerged: (a) PBME was easier to teach about than to practice, (b) several factors contributed to participants' level of depth and authenticity in employing PBME, and (c) teaching place-based statistics was fundamentally different than teaching place-based mathematics. The findings suggest that making a distinction between place-based mathematics education and place-based statistics education would benefit research and practice in both areas. Semi-structured interview protocols are appended.

9. Estimation of Apprentice and Trainee Statistics. Technical Paper
- Author

National Centre for Vocational Education Research and Harvey, Brian
- Abstract
Apprentice and trainee data are reported by the State and Territory Training Authorities to the National Centre for Vocational Education Research (NCVER) on a quarterly basis, starting at the September quarter of 1994. The set of data submitted that quarter is referred to as Collection 1. The sets of data submitted in subsequent quarters are referred to as Collection 2, Collection 3 and so on. At the time of writing, the set of data being submitted is for the June 2009 quarter and is referred to as Collection 60. Of particular interest is the numbers of contracts of training that commence, complete, cancel/withdraw, re-commence, expire or suspend and the time at which these events occur (referred to as the "date of effect"). From these events, the number of contracts in training at a given time can be calculated. Between the occurrence of one of these events and the appearance of the corresponding datum in the national collection, there is a chain of administrative processes that must be followed. It is not unusual for some time to elapse before information about events appears in the national collection. These time gaps are referred to as "reporting lags". Thus, data about events occurring in a given quarter might require several collections to be completely reported. As a result, accurate counts take time to accumulate. However, waiting for the all the data to be submitted reduces their usefulness. In order to get timely information that can be used for monitoring apprentice/trainee activity and formulating policy, a reliable estimate of the "final" counts is required as soon as possible after the quarter in which the events occur. The current method of calculating estimates from the Apprentice and Trainee collection was endorsed in September 2004 by the National Training Statistics Committee. The purpose of this technical paper is to describe: (1) the way data accumulate over many collections; (2) how items derived from the data change as the data accumulates; (3) the endorsed estimation method (developed from the analysis of the above); (4) the formulae for calculating the required estimates; and (5) potential weaknesses in the method. Supporting data is appended. (Contains 4 tables and 8 figures.) [For the accompanying report, "Apprentices and Trainees: September Quarter 2009", see ED508817.]

10. Why Are Young Children Missed so Often in the Census? KIDS COUNT Working Paper
- Author

Annie E. Casey Foundation and O'Hare, William P.
- Abstract
The Decennial Census is the most important data collection activity undertaken by the U.S. federal statistical system. Because census data are used to apportion Congress and draw redistricting lines for thousands of state and local single-member districts to meet the one-person/one-vote guidelines, the census is at the heart of the political system. Also, census data are used to distribute more than $400 billion in federal funds each year, and they are widely used by other government statistical agencies to calculate rates or design surveys. Children are the age group most often missed in the Decennial Census--the reasons range from their living in hard-to-count neighborhoods to the fact that the census form only has space for complete demographic information on six household members. The fact that children are the age group missed most often in the Decennial Census comes as a surprise to many people, even those who have closely followed census issues. Despite the long-standing problem of children being missed in the Decennial Census, little has been done to examine this issue. Missed children might be referred to as the "overlooked undercount" because the undercount of children has been a persistent problem that has been given relatively little attention over time. The high undercount of children challenges the image that the undercount is made up mostly of young adults and people who dodge the census-takers for nefarious reasons. Unlike adults, who may bear some responsibility for making sure they are counted in the census, children are dependent on others to make sure they are included. Yet in 1980, 1990, and 2000, Census Bureau data show children, particularly young children, are one of the groups most likely to be missed in the census. This publication provides some background and information on the undercount of children, describes some theories about why children are missed in the census, and outlines a few ideas for reaching the parents of young children with a message about the importance of being counted in the census. (Contains 2 figures, 1 box, 10 tables and 37 endnotes.)

11. Students' Conceptual Metaphors Influence Their Statistical Reasoning about Confidence Intervals. WCER Working Paper No. 2008-5

Wisconsin Center for Education Research, Grant, Timothy S., and Nathan, Mitchell J.
- Abstract
Confidence intervals are beginning to play an increasing role in the reporting of research findings within the social and behavioral sciences and, consequently, are becoming more prevalent in beginning classes in statistics and research methods. Confidence intervals are an attractive means of conveying experimental results, as they contain a considerable amount of information in a concise format. The objectives of this study are to (1) show that the theory of conceptual metaphor as delineated in contemporary embodied cognition is a useful framework for describing statistics students' conceptions of confidence intervals; and (2) provide empirical evidence from discourse and gesture that graduate students in social science use at least two competing conceptual metaphors for confidence limits that have important implications for the understanding and application of statistics and for the reform of statistics education. In the first metaphor--Confidence Intervals Are Changing Rings Around a Fixed Point ("Changing Ring metaphor")--confidence intervals are moving disks of various diameters covering a fixed but unknown point, like horseshoes of varying widths pitched at a fixed stake. Key to this correct conceptual metaphor is that the interval is a property of a sample but not of the population. Here, the diameter of the disk (i.e., the length of the confidence interval) changes from sample to sample, whereas the location of the stake (i.e., the population parameter or population mean) is fixed across samples but generally unknown. In contrast, the second metaphor--Confidence Intervals Are Changing Points on a Fixed Disk ("Fixed Disk metaphor")--conceptualizes confidence intervals as fixed-diameter disks onto which successive points are placed. In this incorrect metaphor, the population parameter can change from sample to sample. The interval is of a fixed length, and each experiment results in placing a new parameter somewhere onto the fixed-diameter disk. One possible source of this second metaphor is a suspected confusion between acceptance regions in hypothesis testing and confidence intervals, concepts that tend to be taught in close proximity to one another in statistics textbooks. The Fixed Disk metaphor will generally lead to a misinterpretation of the confidence interval that results in inaccurate problem solving. By better understanding students' mental representations of confidence intervals and appealing to the metaphors they convey, the authors hope to improve both statistics instruction and education researchers' uses of statistical tests. Interview items are appended. (Contains 5 tables and 4 figures.)

- Abstract
This study reports on five disciplinary case studies that explore academic value systems as they influence publishing behavior and attitudes of University of California, Berkeley faculty. The case studies are based on direct interviews with relevant stakeholders--faculty, advancement reviewers, librarians, and editors--in five fields: chemical engineering, anthropology, law and economics, English-language literature, and biostatistics. The results of the study strongly confirm the vital role of peer review in faculty attitudes and actual publishing behavior. There is much more experimentation, however, with regard to means of in-progress communication, where single means of publication and communication are not fixed so deeply in values and tradition as they are for final, archival publication. We conclude that approaches that try to "move" faculty and deeply embedded value systems directly toward new forms of archival, "final" publication are destined largely to failure in the short-term. From our perspective, a more promising route is to (1) examine the needs of scholarly researchers for both final and in-progress communications, and (2) determine how those needs are likely to influence future scenarios in a range of disciplinary areas. (Contains 11 notes.)

Jonsdottir, Anna Helga, Bjornsdottir, Audbjorg, and Stefansson, Gunnar
- Abstract
A repeated crossover experiment comparing learning among students handing in pen-and-paper homework (PPH) with students handing in web-based homework (WBH) has been conducted. The system used in the experiments, the tutor-web, has been used to deliver homework problems to thousands of students in mathematics and statistics over several years. Since 2011, experimental changes have been made regarding how the system allocates items to students, how grading is done, and the type of feedback provided. The experiment described here was conducted annually from 2011 to 2014. Approximately, 100 students in an introductory statistics course participated each year. The main goals were to determine whether the above-mentioned changes had an impact on learning as measured by test scores in addition to comparing learning among students doing PPH with students handing in WBH.

- Abstract
The theme of the 39th proceedings of the North American Chapter of the International Group for the Psychology of Mathematics Education (PME-NA) conference was "Synergy at the Crossroads: Future Directions for Theory, Research, and Practice." The metaphor of crossroads was inspired by the conference venue--the historic Indianapolis Union Station, as well as by the state motto, a reference to how Indiana is connected to the rest of the United States. PME-NA 39 includes research presentations, discussion, and reflection focusing on four driving questions connecting to the metaphor of crossroads: (1) What have we learned from the routes we have traversed; what are potential routes for mathematics education research in the future; and what considerations are relevant as we make choices about future directions in mathematics education?; (2) How do we address issues of access and equity within mathematics education today?; (3) How can we lay the groundwork for future crossroads or intersections between theory, research, and practice?; and (4) What barriers within research traditions, educational policy, and teaching practice impede researchers', students', and teachers' success, and how can we work to overcome these barriers? The accepted proposals included 75 research reports, 142 brief research reports, 167 posters, and 13 working groups. Chapters include: (1) Plenary Papers; (2) Curriculum and Related Factors; (3) Early Algebra, Algebra, and Number Concepts; (4) Geometry and Measurement; (5) Inservice Teacher Education/Professional Development; (6) Mathematical Knowledge for Teaching; (7) Mathematical Processes; (8) Preservice Teacher Education; (9) Statistics and Probability; (10) Student Learning and Related Factors; (11) Teaching and Classroom Practice; (12) Technology; (13) Theory and Research Methods; and (14) Working Groups.

- Abstract
Although statistical literacy has become a key competence in today's data-driven society, it is usually not a part of statistics education. To address this issue, we propose an innovative concept for a conference-like seminar on the topic of statistical literacy. This seminar draws attention to the relevance and importance of statistical literacy, and moreover, students are made aware of the process of science communication and are introduced to the peer review process for the assessment of scientific papers. In the summer term 2020, the seminar was conducted as a joint project by the University of Hamburg, the University of Muenster, and the Joachim Herz Foundation. In this article, we present the concept of the seminar and our experience with this concept in the summer term 2020.

21. Exploring Graduate and Undergraduate Course Evaluations Administered on Paper and Online: A Case Study

Perrett, Jamis J.
- Abstract
The purpose of this study was to analyse the students' evaluations of the course and instructor for all statistics courses offered during fall semester 2009 at a large university in the southern United States. Data were collected and analysed for course evaluations administered both online and on paper to students in both undergraduate and graduate courses. Unlike most previous studies on this subject, class section rather than student was treated as the unit of analysis. It was of specific interest to verify prior research findings that evaluation surveys administered online would not result in lower course and instructor ratings and lower response rates. The results showed that there is not sufficient evidence within the collected data to conclude that either course and instructor ratings or response rates are lower for evaluations administered online (online evaluations) than they are for evaluations administered on paper (paper evaluations). Of secondary interest was whether class ratings would be associated with students' attendance and a comparison of variability among answers for undergraduate vs. graduate students. It was observed that class and teacher ratings were not related to students’ attendance and individual students did not tend to give the same answer for every question on their survey.

- Abstract
This paper reports on the potential for engaging students in an activity that considers the interconnectedness of the five Big Ideas of Statistics in the context of conducting random trials. In the study, two classes of Year 6 students (aged 11-12 years) used "TinkerPlots" to determine the sample space of a "Mystery Spinner." Analysed for this paper were data collected from entries made in completed workbooks while engaged in the learning activity and responses to relevant questions in an end-of-year questionnaire from 27 students. The results indicated using an activity that included a probability model contributed to students working mathematically with percentages and frequencies and supported the development of intuitions about randomness and informal inference. This was promoted by students analysing the variation in the distribution of data and describing their expectations about an unknown sample space.

24. Cleared for Takeoff: Paper Airplanes in Flight

Reeder, Stacy L.
- Abstract
As middle school mathematics becomes more abstract, it is imperative for teachers to introduce concepts in ways that are interesting and meaningful to students. Since her students struggled at times to stay engaged in mathematics and seemed to have difficulty developing conceptual understanding, the author looked for ways to create learning contexts that would be noteworthy and relevant. Working with data seemed to lend itself readily to contexts that were appealing to students. To give her students additional experience with measures of central tendency and data collection, she developed an activity that involved making and flying paper airplanes. This lesson, which ultimately focused on measures of central tendency, also addressed measurement, scatter plots, and the four main forces of flight. (Contains 5 figures.)

Johnson, Danny J.
- Abstract
This hands-on project uses a paper helicopter to teach students how to distinguish between common and special causes of variability when developing and using statistical process control charts. It allows the student to experience a process that is out-of-control due to imprecise or incomplete product design specifications and to discover how the process can be brought into control through the use of standardized product specifications and associated construction procedures. It also allows the student to experience common causes of variability, to distinguish these from the special causes of variability resulting from the incomplete design specifications, and to discover how standardization reduces process variability. The project has been used in both undergraduate and MBA classes and demonstrates these concepts in a way that is easy for the student to understand and remember.

27. Unequal Pathways through American Universities. Discussion Paper No. 1391-11

- Abstract
Student pathways through the American higher education system are complex and entail more than the choice between continuation and dropout. The four-year college system requires students seeking a bachelor's degree to pass through a series of transitions that are marked by the achievement of credit thresholds in each year of study. At those junctures students make critical decisions about their progress: whether to enroll for sufficient credits to ensure timely completion, whether to enroll for fewer credits, or whether to leave school for a limited period of time. This project overcomes the simplistic view of discrete choices between enrollment and nonenrollment and takes a close look at the cumulative nature of the attainment of U.S. students at four-year colleges and the social inequalities arising in this process. Detailed transcript data from the National Educational Longitudinal Study (NELS-88) and multinomial transition models provide evidence on the shape of and social inequality in four-year college careers. We describe distinct trajectories through college and show that they strongly depend on students' decisions at earlier stages of their college careers. Transitions through college are also found to be strongly related to students' socioeconomic backgrounds. In addition, we show that the penalties incurred from unfavorable earlier choices is greater for disadvantaged students. By fully appreciating the cumulative nature of educational pathways through college we provide an important new view on the complex routes to college completion and trace an important source of the socioeconomic gap in college completion. The relatively rigid structure of the U.S. four-year college system appears to produce strong path-dependent and status dependent cumulative advantages for high-status students. Appended are the following tables: (1) Variable Descriptions; (2) Multinomial Regressions (Odds Ratios); and (3) BA Completion (Odds Ratios). (Contains 4 tables, 4 figures, and 10 footnotes.)

28. Designing Incentive Systems for Schools. Working Paper 2008-16

Vanderbilt University, National Center on Performance Incentives and Neal, Derek
- Abstract
This chapter considers the design of incentive pay systems for teachers and principals and the challenges facing policy makers who seek to design them. The author argues that policy makers must direct the efforts of teachers and principals toward schools' mission--the acquisition of skills and knowledge among children--and must find ways to link the compensation of teachers and principals to the value of the educational services provided by their schools. However, the nature of the educational process creates at least three important challenges for those who design incentive systems for educators. Even when reliable measures of student achievement are available, it is difficult to value the outputs of schools and also difficult to identify whom within different schools is responsible for the observed variation in the outputs of schools. Further, the process of assessing achievement under high-stakes may create undesirable re-allocations of resources among various types of learning activities within schools. The author's goal is to explain and analyze how these challenges affect the design of incentive systems for teachers and principals. (Contains 1 table and 19 footnotes.)

- Abstract
The EMERGENCE project carried out by the IES (Institute for Employment Studies) aimed to measure "eWork" at a global level. For the project, eWork was defined to mean any type of work that involves the digital processing of information and that uses a telecommunications link for receipt or delivery of the work to a remote employer or business client. Providing an overview for discussion, the project report first outlines the definition of eWork and then addresses the question of the value of monitoring eWork and points out its relevance to policymakers in many disciplines. Finally, the report discusses the inadequacy of the existing sectoral and occupational classification systems to capture the characteristics and dynamics of eWork, and suggests some issues for consideration by European agencies involved in the collection and analysis of statistics on the information economy. The report concludes with several recommendations, including the following: (1) European labor force surveys should include questions that make it possible to identify people who work at or from their homes or from multiple locations using computers with a telecommunications link to employers or clients; (2) the updating of occupational classification codes should include a process for capturing information on the new jobs that are emerging in the information economy and synchronizing codes throughout Europe; (3) methods for collecting information about earnings for such occupational groups should be developed; and (4) the data from such studies should be updated regularly through additional surveys.

- Abstract
The rapidly increasing capacity of technology to collect, organize, and manage data has spurred changes in the practice of statistics: new methods of collecting data, large data sets, new forms of data, different ways to visualize and represent data, and recognition of the importance of being able to understand and to communicate data-based arguments and findings from the perspective of data consumers and data producers. Using a narrative review based on Delphi methods, we asked leading members of the statistics education community to describe trends they have observed in the field and to identify interesting and relevant papers related to those trends. We received 24 responses and over 200 suggestions for papers. Our analysis included papers published in journals, book chapters, conference proceedings, handbooks, and curricular documents. We focused on future directions for statistics education research, and thus included articles based on opinion or principles if the arguments made a strong case supported by evidence as to why the idea was needed. From our analysis of 50 papers in this review, we suggest four emerging themes in statistics education research, challenging what should be taught and suggesting new ways of thinking about the teaching and learning of statistics: Data Science, Visibilizing Statistical Concepts, Social Statistics, and New Contexts for Learning. The review focuses on articles from 2017-mid 2022 and highlights the relevance and importance of each theme. Our choice of a particularly important paper for each theme is annotated in the references.

35. Bureau of Labor Statistics (BLS) Family Budgets Program. The Measure of Poverty, Technical Paper IV.

Department of Health, Education, and Welfare, Washington, DC. Office of the Assistant Secretary for Planning and Evaluation. and Sherwood, Mark K.
- Abstract
This paper discusses the three hypothetical market baskets of goods and services for which the Bureau of Labor Statistics publishes annual cost estimates. This program is referred to as the standard budgets or family budget program. The family budget program provides: 1) estimates of budget levels originally constructed to represent standards of living; 2) interarea indexes of "living costs" based upon these budget estimates; and 3) adjustment factors to convert the budgets for other family sizes and types. Attention is given to the limitations of the family budgets as measures of income adequacy and to their use as indexes of interarea cost-of-living differences. Briefly, the general limitations of the budgets program with respect to defining poverty are: 1) as measures of income adequacy, 2) as measures of interarea cost of living differences, and 3) as adjustment of factors for various sizes and types of families. The paper also discusses the manner of living represented by the market baskets program, price measurement problems, geographic cost of living comparisons, and equivalence scales. In addition, it includes a short section which discusses areas for future research in this program. (Author/AM)

- Abstract
Experimenters sometimes wish to estimate for a particular dependent variable the proportion of total group variance that is associated with mean differences among fixed treatments or subject classifications. Hays (1981) represents this proportion by the parameter omega squared. A point estimate may be easily computed as a function of the number of treatments, the total sample size, and the mean squares between and within treatments. This paper presents tables which facilitate the construction of 90 or 95 percent confidence intervals for omega squared. (Author)

- Abstract
It is increasingly recognised that to be informed citizens and to participate fully in the workforce requires an understanding of statistical data and risk. Such understanding is underpinned by statistical reasoning. It has been shown, however, that students have difficulty moving from concrete representations and procedural mathematical statistics to the context-based appreciation of data drawing on proportional reasoning that is becoming increasingly necessary. Based on the Statistical Reasoning Learning Progression (SRLP), this paper examines the barriers to shifting to higher-order thinking.

38. Using Machine Learning Explainability Methods to Personalize Interventions for Students

Hur, Paul, Lee, HaeJin, Bhat, Suma, and Bosch, Nigel
- Abstract
Machine learning is a powerful method for predicting the outcomes of interactions with educational software, such as the grade a student is likely to receive. However, a predicted outcome alone provides little insight regarding how a student's experience should be personalized based on that outcome. In this paper, we explore a generalizable approach for resolving this issue by personalizing learning using explanations of predictions generated via machine learning explainability methods. We tested the approach in a self-guided, self-paced online learning system for college-level introductory statistics topics that provided personalized interventions for encouraging self-regulated learning behaviors. The system used explanations generated by SHAP (SHapley Additive exPlanations) to recommend specific actions for students to take based on features that most negatively influenced predicted learning outcomes; an "expert system" comparison condition provided recommendations based on predefined rules. A randomized controlled trial of 73 participants (37 expert-system condition, 36 explanation condition) revealed similar learning and topic-choosing behavior between conditions, suggesting that XAI-informed interventions facilitated student statistics learning to a similar degree as expert-system interventions.

- Abstract
Two case studies of Australian primary school students tracked changes in their data interpretation and representation over three years. Students were engaged in predictive reasoning tasks based on their interpretation of a data table showing temperature change over time. Students' explanations and graphical representations were collected at the beginning of Years 3 and 4 and the end of Years 4 and 5. The first case study was a student mathematically weaker than her peers while case study two was within the average range for her year. Despite differences in starting points, both case studies followed a similar developmental sequence of predicting, interpreting and representing, with the first case generally lagging one stage behind the second case. Similarities and contrasts between the two students are discussed.

Wisconsin Univ., Madison. Research and Development Center for Cognitive Learning. and Brumet, Michael E.
- Abstract
Bayesian statistical inference is unfamiliar to many educational evaluators. While the classical model is useful in educational research, it is not as useful in evaluation because of the need to identify solutions to practical problems based on a wide spectrum of information. The reason Bayesian analysis is effective for decision making is that it defines probability as a measure of opinion or belief, rather than as long-term frequency. Defining probability as a measure of opinion or belief enables the Bayesian investigator to consider a wider range of information than is possible with the traditional model. Personal expertise, logical analysis, and soft data from a wide variety of sources serve to shape opinion about a state of nature, with experimental data providing additional information either for or against the prior opinion of the evaluator. In classical statistics, prior knowledge or opinion is ignored. However, when practical decisions must be made the Bayesian stresses that all knowledge should be brought to bear on the problem rather than just an isolated set of data. Because of the decision-making orientation of the evaluator, the Bayesian model should be considered as an alternative to classical inference. Since the Bayesian model views probability as a measure of opinion rather than as a long-term frequency, the statistical requirements for it are actually greater than for the classical statistician. Use of a wider range of distributions than with classical statistics demands more statistical skills than many evaluators currently possess. However, the questions raised by the Bayesian model are useful even if the model is not totally adopted. (Author/RC)

- Abstract
Comparisons of students' educational performances are usually based on test and examination results. However, for such comparisons to be valid, it is suggested that evaluations must be made on some common basis since many educational and employment decisions are based on these evaluations. Standardized tests, often used when comparisons are to be made, offer some guarantee of a common evaluative basis, even though they may contain measurement errors. Among the many transforming and scaling work techniques that have been suggested, two measurements are considered useful in terms of groups of scores, that is, central tendency (mean and median) and dispersion (standard deviation and interquartile range) measures. It is suggested that while transformations are required in order to validate results from different examinations, one should consider what purpose the transformation is to serve. Also, discussed are transformations that convert marks to T scores and the differences among percentiles, ranks, and standard scores. It is concluded that certain basic educational problems are revealed when scaling or transformation techniques are used. (JS)

- Abstract
Included in this bibliography are resource materials available to both college instructors and students on statistical applications in geographic research. Two stages of statistical development are treated in the bibliography. They are 1) descriptive statistics, in which the sample is the focus of interest, and 2) analytical statistics, in which the population is the primary interest. For each of the sections, a short introductory statement is made concerning the general nature of problems investigated using that technique, where applicable. The bibliography treats 34 categories of geographic statistical concepts, such as measurement, set theory, geographic data, geography matrix, computer applications, sample designs and methods, descriptive statistics, index construction, analysis of variance, geostatistics, point pattern analysis, among others. Not included in the bibliography are references to sample space, expected values, random variables, population and sampling distributions. Entries are listed alphabetically by author, and include the title, source, number of pages, date, and place of publication. (Author/JR)

- Abstract
The testing of research hypotheses is directly comparable to the dichotomous decision-making of medical diagnosis or jury trials--not ill/ill, or innocent/guilty decisions. There are costs in both kinds of error, type I errors of falsely rejecting a null hypothesis or type II errors of falsely rejecting an alternative hypothesis. It is important to consider the power of a statistical test (that is, the likelihood of avoiding type II errors) as well as the significance level (the likelihood of avoiding type I errors) before an experiment is begun. Techniques for estimating the power of a statistical test for a particular experimental design are presented. (CTM)

Informality is a dynamic and multidimensional concern that demands gender-sensitive data. In 2018, globally, more than 60% of employment was informal. However, global averages hide that in more countries the share of women in informal employment exceeds that of men. Also, women in the informal economy are often in the most unprotected situations - as domestic workers, home-based workers and contributing family workers - where a lack of visibility can increase their vulnerability. The ILO and its partners are working to engender informality statistics to improve gender data and support countries to respond to data needs on women's economic empowerment. This working paper was written to support the ILO Working Group for the Revision of the standards for statistics on informality. It explores the demand for gender data on informality and the measurement challenges faced. The paper highlights the opportunities emerging from the revision of statistical standards on informality that are set to be adopted in 2023. [ABSTRACT FROM AUTHOR]

- Abstract
This study aims to investigate the advantages of implementing multimedia resources in the teaching and learning environment of mathematics and statistics. It examines the use of tablet PCs to create video learning resources. Such practices allow lecturers to provide additional learning support to students via the learning platform Moodle. This paper discusses the experiences of three lecturers in developing a technology-based, interactive teaching method to support student learning. The results found that "solved examples" in the video resources are useful in demonstrating topics about statistics. Furthermore, the paper encourages lecturers to learn from their experiences and develop learning resources to enable students to better engage in the learning process.

- Abstract
Random sampling and random allocation are essential processes in the practice of inferential statistics. These processes ensure that all members of a population are equally likely to be selected, and that all possible allocations in an experiment are equally likely. It is these characteristics that allow the validity of the subsequent calculations that use probabilistic reasoning. This paper suggests that despite the importance of these processes, students may poorly understand the characteristics of these processes, and the reasons for them. The paper concludes with suggestions for the improvement of teaching these topics.
