[Use of nonparametric methods in medicine. VII. Kendall's coefficient of concordance in several sequences].

The authors describe the procedure, suggested by Kendall for evaluation of the concordance of several sequences. Kendall's coefficient, called also coefficient of concordance, can be used when it is possible to assess the sequence of investigated variables. The calculation procedure and interpretation of the coefficient is explained on a simple example. For evaluation of significance tables of critical values are presented for 1% and 5% levels of significance.
