Solution
The appropriate test to use instead of the repeated measures t-test, if the Shapiro-Wilk test indicates that your data is not normally distributed, would be the Wilcoxon test. This test is a non-parametric alternative to the paired or repeated measures t-test and does not assume normal distribution of the data.
Levene's test is used to assess the equality of variances for a variable calculated for two or more groups. An independent-sample t-test is used when you have two separate groups of participants, which is not the case here. The Mann-Whitney U test is a nonparametric test of the null hypothesis that it is equally likely that a randomly selected value from one sample will be less than or greater than a randomly selected value from a second sample, which is not applicable in this scenario.
