AThree sets
BFour sets
CTwo sets
DOne set
Answer & Solution
Correct answer: C. Two sets
1. The F statistic is a ratio, so each part carries its own count.
2. To calculate the F ratio, two estimates of the variance are made.
3. There are two sets of degrees of freedom.
4. One set is for the numerator of the ratio.
5. The other set is for the denominator.
