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.
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".
