Test U Mann Whitney. It is considered to be the nonparametric equivalent to the two sample independent t test. A mann whitney u test sometimes called the wilcoxon rank sum test is used to compare the differences between two independent samples when the sample distributions are not normally distributed and the sample sizes are small n 30.
A mann whitney u test sometimes called the wilcoxon rank sum test is used to compare the differences between two independent samples when the sample distributions are not normally distributed and the sample sizes are small n 30. Your variable of interest should be continuous and your 2 groups should have similar values on your variable of interest. A similar nonparametric test used on dependent samples is the wilcoxon signed rank test.
