12. A researcher reports an outcome of one factor ANOVA for independent samples as F(2, 36) = 5.22. What was the total number of participants in the study?

• A. 36 total participants.

• B. 38 total participants.

• C. 39 total participants.

• D. 29 total participants

13.A researcher reports an outcome of one factor ANOVA for independent samples as F(2, 36) = 5.22. Based on this outcome, what is the correct statistical decision?

• A. Fail to reject the null hypothesis with either, p < .05 or p < .01

• B. Fail to reject the null hypothesis with p < .05 but reject with p < .01.

• C. Reject the null hypothesis with either, p < .05 or p < .01.

• D. Reject the null hypothesis with p < .05 but fail to reject with p < .01.

Answer 1

Ans:

8)

Option B is correct.

MSbetween should be about the same size as MSwithin

7)

Option B is correct.

MSbetween should be greater than MSwithin.

Between group variance should be greater than the within group variance.

12)

df(between)=k-1=2

k=3

df(within)=N-k=36

N-3=36

N=36+3=39

Option C is correct.

39 total participants.

13)

p-value=FDIST(5.22,2,36)=0.0102

As,p-value<0.05,but p-value>0.01

Option D is correct.

Reject the null hypothesis with p < .05 but fail to reject with p < .01.
