Finding the number of observations N from ANOVA

[hassan.mahfooz]

I would like to know how to calculate the number of observations n from ANOVA table if the following is given:

RSS = 400

Total DF = 49

MSR = 1.93

You don’t give enough information to solve the problem.

You should be able to get it from DF, if you know k

I would like to know how to calculate the number of observations n from ANOVA table if the following is given:

RSS = 400

Total DF = 49 Just add 1… Total DF= n-1 so 49=n-1 —> n=50

MSR = 1.93

You don’t give enough information to solve the problem. It looks as if he did.

You should be able to get it from DF, if you know k. If you have total DF (n-1), then you don’t need K…just add 1 back to total DF

Um . . . yes: n = 50.
