Hi everyone, i performed a T-test, and for the C.I. , I got 3 lines in the t-test about this. The first is for "group A" second is for "group B" and third is for "Diff(Group A - Group B)" Now, I NEED TO DO AN ANALYSIS ON THE VARIABILITY OF GROUP A AND GROUP B, whether I should use the line "Diff(Group A- Group B)" or the calculations that I get by myself from the subtraction of lower bound of CI and upper bound of CI in different groups? Thank you ... View more

Hi everyone. If I got a data like: 1 1 4 6 7 3 2 5 7 8 9 5 3 2 6 8 9 0 9 0 9 7 6 5 4 5 7 8 9 8 how can i put them into different arrays alternatively? like the first, third, fifth, seventh.....,29th (the number of obeservation = old) in one group and the second, forth, sixth,....,30th (the number of obersvation = even) in another group. Thank you ... View more
