Because there might be multiple colList Y, I did a loop to iterate every single colListY items and create a t-test. For every colListY item, it opens a window with the t-test. Example: If my colListY have 3 elements, namely A,B,C, and colListX being Time, I would have 3 Windows of t-test, A by Time, B by Time and C by Time. May I know is there anywhere I could join all the Oneway analysis in one window after the looping? Thank you so much!
