A graduate student who began to conduct scientific research is constantly confronted with the problem of statistical data processing. All possible criteria: Chi-square criterion or Fisher Criterion, Student's t-test, Wilcoxon's criterion or Mann-Whitney Criterion and when are they eligible? Is it a pair test? Where to get the value of p and when can it be used?
