[Comparison of the parts in relation to some problems of the statistical processing and planning of cytological experiments].

A possibility is studied of using phi-transformation for comparison of portions in homogenous totalities with intra-group variability. The phi value distribution is approximated satisfactorily by normal distribution, beginning from a certain amount of observation (n) depending on P, P being a portion of cells (individuals) with the character under study. On this basis, a method of statistical treatment and experiment planning is proposed.
