Sign Test Table Value. The following table provides the critical values for two tailed tests. The sign test like the wilcoxon signed ranks test is a non parametric alternative to the repeated measures t test.

This table shows the value of z statistic and the probability value. If the sample size is large enough a formula for a z statistic can be used and it is.
