In this paper we analyze the use of statistics and associated
problems, in three Czech biological journals in the year 2000.
We investigated 23 articles Folia Biologica, 60 articles in
Folia Microbiologica, and 88 articles in Physiological Research.
The highest frequency of publications with statistical content
have used descriptive statistics and t-test. The most usual
mistake concerns the absence of reference about the used
statistical software and insufficient description of the data.
We have compared our results with the results of similar studies
in some other medical journals. The use of important statistical
methods is comparable with those used in most medical journals,
the proportion of articles, in which the applied method is
described insufficiently is moderately low.
