Hi.Please help if someone can.
Problem:
I have 2 matrices
Eg
matrix 1:
Freq None Some
Heavy 3 2 5
Never 8 13 8
Occas 1 4 4
Regul 9 5 7
matrix 2:
Freq None Some
Heavy 7 1 3
Never 87 18 84
Occas 12 3 4
Regul 9 1 7
I want to see if matrix 1 is significantly different from matrix 2. I
consider using a chi-squared test. Is this appropriate?
Could anyone advise?
Many thank you.
Aaral Singh
