2. Suppose we have N = 100 and I = 3. In ANOVA, the numerator degrees of freedom for the F-statistic are = ?
and the denominator degrees of freedom are = ?
3. If N = 105, what is DFT?

1.SST
2.SSG
3.SSE
4.DFT
5.DFE
6.DFG
Explanation / Answer
A) The variation due to variation between the group means-- SSG
B)N - I --DFE
C) N-1 --DFT
D) I-1 --DFG
E) The variation within the groups--SSE
F)The total variation in the data--SST
2)numerator degrees of freedom for the F-statistic are =I-1=3-1=2
3) DFT =N-1=104
4)SSE =SST-SSG=854-104=750
