A mérés és a méréselmélet néhány alapkérdése.

Statistical analysis has a special relationship to measurement. For it, measurement and measurement theory not only provide the data on which analysis is based, but are also a source of important uncertainties in theoretical, methodological and applied research. A detailed presentation of measurement issues is therefore justified, together with the different approaches and the arguments behind them. After a careful discussion of the everyday and scientific meanings of measurement, the paper deals with the different meanings and conceptions of measurement, and then turn to the drastic change in meaning in social statistics in the mid-20th century. Then the theory of measurement scales, their criticism and proposals for expansion will be discussed, and finally some of the specific aspects of Likert-type statements that cannot be placed within the framework of measurement scales will be examined. One of the conclusions of the paper is that the Stevens system of measurement scales cannot be regarded as an adequate description of data types. [ABSTRACT FROM AUTHOR]
