Wilcoxon Signed-Rank Test

[ranamanish674zu]

Description

The Wilcoxon Signed-Rank Test is a non-parametric statistical test used to determine whether there is a significant difference between paired observations. It is suitable for ordinal or continuous data that do not meet the assumptions required by parametric tests like the paired t-test. The test ranks the absolute differences between paired observations, assigns ranks based on the magnitude of these differences, and calculates a signed rank statistic. The test assesses whether the median of the differences significantly differs from zero, indicating a change or effect between paired samples. A non-parametric test used to compare two related samples, matched samples, or repeated measurements on a single sample to assess whether their population mean ranks differ. Fixes #437
