I'm conducting a 2x3 mixed between-within subjects ANOVA (group x time). I have 20 participants, 10 for each group, who undergo all the 3 measures over time.
Levene's test of equality of variances is not significant for both time1 and time3. Unfortunately, on time 2, group1 (M = 2,869, SD = 1,571) and group2 (M = 6,706, SD = 3,521) have variances significantly not homogeneous (p = 0.016). Is this too bad? Can I trust the ANOVA results?
