Homework Help: statistics

Posted by Helen on Wednesday, April 2, 2008 at 2:08pm.

n=15 and there are 3 groups

These data are analyzed by an ANOVA, and the resutls are reported in the following summary table. fill in all missing values in the table.

* All that is given in the table is the MS(mean square) within treatments=20 and F=4 (f-ratio)

I have to find the SS Between and Within treatments.

The df for between and within treatments, this what I got:
df total=44 (n=15, (15)(3)=45, N=45, dftotal=N-1, 45-1=44)

df between= k-1= 3-1= 2


df within= N-k=45-3= 42


-My question is how do I find the MS within treatments
-SS for within and between treatments,

when only the F (4) is given, the MS of between treatments is given (20), and the df's that I calculated above?

Please help! Thank You
