A paired sample, two-sample t test is used to compare the means of two related samples, whereas a Wilcoxon signed-rank test is used to compare the medians of two related samples. Both tests are nonparametric and are appropriate when the data do not meet the assumptions of normality and equal variances for the t-test. Therefore, the Wilcoxon signed-rank test is the best choice.
