Find the critical F-value for a one-way ANOVA given:

α = 0.01

dfb = 30

dfw = 14

a. 2.72

b. 3.34

c. 4.21

d. 1.98

e. 3.00

In which direction is the F distribution skewed?

a. Positively skewed

b. Negatively skewed

c. No skew

If our calculated F is LARGER than our identified critical value from the F-table, what decision would we make about the null hypothesis?

a. Reject the null hypothesis

b. Fail to reject (i.e., retain) the null hypothesis

Which source of variability in ANOVA reflects any potential “treatment effect”?

a. Variability within groups

b. Variability between groups
