On the choice of method of statistical data processing in medicosociological research

The type of data distribution in the study should be evaluated with the help of mathematic-statistical criterion. Parametric tests are used when the obtained data distribution is considered as normal. The type of distribution for nonparametric tests is of no importance. The suggested algorithm will help the investigator to classify the facts, develop a study design and choose the best technique of processing obtained information. Therefore, mathematic statistics as applied to medico-sociological study may help to define the purpose, develop the study design, choose the statistic method for revelation of statistically significant difference during an analysis of obtained results and drawing the conclusion.
