Hello all,
I am planning to develop Normative Values according to Age and Gender wise but I am quite confused with the sample size for each cell of age and genders like 11-20, 21-30, 31-40, 41-50, 51-60, 61-70, 70 & above for male and female. So can anyone suggest to me, how to do sample size calculation?
Waiting for your answer!!!
Thank you
