Hi, Dr. Robinson. Should i report data from equal variance is not assumed row if the levene test is less than 0.05? The lower limit of confidence of interval is negative and upper is positive. Now, how to report the results in APA 7 format? Also, if the study's hypothesis is one tailed, the 2 tailed sig. must be halved, right? Thank you so much iin advance

Hi, what if one group is not normally distributed?

Hi, thanks for your question. You could consider doing a non-parametric equivalent, like the Mann-Whitney U test.
