Sir, if the variables are measured on likert scale. Then which test should be used under repeated measures design? Paired t test or wilcoxon signed rank test?
how2stats answers this in the video about paired t-test assumptions likert items by themselves are ordinal, but as likert scales are the sum of the items they can be treated as interval scale. but should be 5-point likert minimum (the more points the better)
You saved me with this clear explanation, thank you so much
