The Wilcoxon signed-ranks T test is a non-parametric test used to compare two related samples. The test statistic T is calculated based on the ranks of the differences between pairs. A smaller value of T indicates that the observed differences are not likely to occur by chance, leading to the rejection of the null hypothesis. This is because a small T value suggests a systematic difference between the paired samples, rather than random variation.
