I am running mixed ANOVA as repeated measurement analysis for cognitive score at 2 time points for 2 groups (blood pressure low vs. High). The the score at time 1 was normally distributed and at time 2 was not normally distributed so I QURT transformed.
Can I still use mixed ANOVA? or both scores should be of same scale/ units? if both should be same, what should i do, transform time 1 or use the original time 2?
