Hi everyone,

I have the following dataset:

SubjectID Training Before After
1 0 1 0
2 0 1 0
3 0 0 0
4 0 1 1
5 0 0 1
6 0 1 0
7 0 1 0
8 0 0 0
9 1 0 1
10 1 0 1
11 1 1 1
12 1 0 0
13 1 1 0
14 1 0 1
15 1 0 1
16 1 1 1

Training Column, 0 - no training, 1 - undergo training program
Before - win/lose before the training group undergo training
After - win/lose after the training group undergo training

How can I use chi square to see if the is a effect in training?
Or is there other methods that I can use?

Thanks a lot for the help! =)

maybe you can create one new variable for your before-after thing:

1= lose lose
2= win lose
3 = lose win
4 = win win


then do a crosstab chi-square with training yes/no
