WebThe sign test and the Wilcoxon signed-rank test are possible alternatives to the paired t-test in the case of two dependent samples. The Wilcoxon rank-sum test (also known as the Mann-Whitney U test) is a possible alternative to the two-sample t-test in the case of two independent samples. WebPaired samples test are used when the same group is tested on multiple occasions. The nonparametric alternative for a dependent (paired) samples t test is the Wilcoxon signed ranks test. Back in Chapter 4, the paired example used theoretical data of NFL quaterback development again looking at passing yards per game. The dataset can be found here.
