Course Description:
The development of Hungarian statistics, a brief overview of its history. The institutional framework of official statistics (UN Statistical Division, Eurostat, The Hungarian Statistical Service). Basic concepts: statistics; the population and criteria; statistical series and tables; measurement, measurement scales, data accuracy; calculated averages: averages; ratios. Quantitative analysis of a population I: frequency, relative frequency; class intervals; graphical illustrations; sum of values, relative sum of values; cumulation; situation indicators (mean, mode, median, quantile). Quantitative analysis of a population II. : variance indicators (spread, mean deviation, standard deviation, relative standard deviation, mean difference). Quantitative analysis of the population III: shape indicators (asymmetry, peak); concentration (Lorenz curve, Herfindahl-Hirschman index); additional graphical charts (age tree, box plot). Simple analyses by time criterion. Multi-criteria analysis of a manifold: analysis of simple tables; analysis of clustering tables; analysis of combinatorial tables (association, mixed relationship, correlation). Comparison of composite intensity ratios: difference decomposition; quotient decomposition. Index calculation: comparing two periods (volume, price, value; average forms of indices); comparing several periods; spatial comparisons; some important practical index numbers.

7. Test 1
8. Contingency tables I. Measures of association.
9. Contingency tables II. Mixed relationship.
10. Contingency tables III. Correlation.
11. Comparison with the method of standardization.

13. Test 2
14. Makeup exams

Assessment: Grade in this course is calculated numerically based on total points/percentages of the two tests although the instructor may raise or decrease it by one grade based on the active/inactive participation in classes or the level of the homework. Test 1 takes place on 25th October 2023. A maximum of 50 points can be earned. Test 2 takes place on 6th December 2023. A maximum of 50 points can be earned. Students may get homework, which should be handed in until the next lesson or presented in some minutes. If the student does not show up or there is no homework prepared, the total performance decreases by 10 points per homework at the end of the semester before the final grading. Grading: 5 (excellent): 87 – 100 4 (good): 75 – 86 3 (satisfactory): 63 – 74 2 (pass): 51 – 62 1 (fail): 50 or less Should a student accumulate a total of 50 or less, an additional chance is given to him/her to meet the requirements. This make-up exam takes place on 13th December 2023, and consists of all the topics of the semester. Grading: same proportions applied as above displayed.
