This sign test calculator can be used to evaluate the results of a repeated-measures study that compares two treatment conditions. The sign test, like the Wilcoxon signed-ranks test, is a non-parametric alternative to the repeated-measures *t*-test.

To use the calculator, simply enter your paired treatment values into the text boxes below, either one score per line or as a comma delimited list, and then press "Calculate". Remember, because the sign test is for *paired* values, you need to have the same number of scores in both treatment conditions.

Treatment 2

Significance Level:

One-tailed or two-tailed hypothesis?:

Add your data to the text boxes above, select your significance level, whether you want a one-tailed or two-tailed *p*-value, and then press "Calculate".
