| Sumario: | The article discusses methodical peculiarities of using descriptive statistics for variable in different scales taking into account partition law and. presents the analysis of conditions of transfer of revealed sample regularities to the universe. The aim. of the work was to describe methods and. peculiarities of using descriptive intragroup statistics. It was determined that choice of parameters of descriptive statistics was based on two principles: 1) adduction of set of descriptive characteristics of central trend, value of dispersion and form of distribution in studied group; 2) adduction of confidence intervals of parameters of sample distribution in case of normal (or connected with normal) partition law. It was concluded that at the description of primary data it is necessary to adduct histogram of primary data imposed on the graph of chosen partition law; full description of observed data in groups with description of sample method of their obtaining; parameters and. criteria that prove rejection or choice of partition law; values of parameters of universe (in case of normal distribution). |
