WebDisambiguation. 1 sample Wilcoxon non parametric hypothesis test is a rank-based test and it compares the standard value (theoretical value) with the hypothesized median. Usually, the t-test depends on the sample mean which is not so stable in heavy-tailed distribution; hence Wilcoxon test efficiency is high when compared to the t-test.
