ANALYSIS OF REPARTITION FORM IN DISTRIBUTIONS OF FREQUENCIES
Elisabeta R. ROSCA
The paper „The Analysis of Repartition Form in the Distributions of Frequencies” presents an introduction in the study of distribution of frequencies, which have some characteristic features by the nature and the group degree of data, by which existing classifications and variation series, unidimension and multidimension series etc. The paper emphasizes that the statistical analysis of series of distributions is based on the comparison of the empirical distributions with theoretical distributions, o n the comparison of parameters of theoretical distributions with the computed values by using the empirical distributions data. The paper presents the indicators of interquartilical and interdecilical variation, the principal methods of asymmetry analysis such as the graphic method and the analytic method based on the estimation and the interpretation of asymmetry coefficients established as relations between the indicators of central tendency or between the individual values and central tendency indicators . Also are presented some aspects concerning the computing and analysis the indicators of peakedness/arching.
interquartilical and interdecilical variation, symmetrical and asymmetrical series, coefficients of asymmetry, absolute and relative densities of frequencies, degrees of peakedness.
