Hi,
I am comparing two ordinal groups, the groups are paired. I wanted to
examine the shift in the groups, the two groups consist of being small,
medium and large.
I am really interested in seeing if there has been a shift towards small. I
was going to code the data 1, 2, 3 and calculate the difference in the two
groups and then test if the mean difference is less than 0, using a Wilcoxin
signed rank test.
Is this an appropriate approach to take to investigate this problem?
Thanks you for all your help.
