STATISTICAL ANALYSIS APPLIED TO THE DATA ON CONSUMER MONETARY EXPENDITURE IN BULGARIA.

The current paper studies data concerning consumer monetary expenditure in Bulgaria. They are structured and saved in several tables of a built data base. The considered objects are 10 different expenditures. A statistical analysis applied to these data on consumer monetary expenditure in Bulgaria is presented for the time period 2012-2021. The necessary information is searched and extracted from the indicated data base. As a result of the performed analysis of variance and Tukey's test four groups with statistically proven differences are obtained for the examined expenditures, average per household. A similar conclusion can be formed about the considered expenditures, average per person. As a whole, consumer monetary expenditure, average per household, increased in eight of the listed ten years. A quite small decline is found during 2016 as well as 2020. It is 1.36% for the first of the listed years and 1.32% for the second one. Approximately the same results are established for the consumer monetary expenditure average per person, where an insignificant decrease is calculated only for 2020. [ABSTRACT FROM AUTHOR]
