Question

1. A researcher wrote a sentence describing the results of an Independent ANOVA that she performed. The statistical information from her study included the following information: F(2,33) = 10.88, p < .05, MSE = 5.00, η2 = 0.40. Using this information, how many people were in this study?

A. 36

B. 35

C. 165

D. 33

3. A researcher wrote a sentence describing the results of an Independent ANOVA that she performed. The statistical information from her study included the following information: F(2,33) = 10.88, p < .05, MSE = 5.00, η2 = 0.40. Does this researcher need to do post hoc tests?

	A.	Yes, the overall ANOVA was significant and there are more than two groups.
	B.	Yes, the effect size for the overall ANOVA was large, whcih means the ANOVA was significant.
	C.	No, the overall ANOVA was significant but there are only two groups.
	D.	No, the effect size for the overall ANOVA was large, which means that all pairwise comparisons will be significant.

Answer 1

1.) In this

k-1 = 2

Then k=3 groups

As N-k = 33

Thus , N =36 people (option A)

2.) Groups = 3 (option C)

3.) In this

3 groups

P- value < 0.05

So, ANOVA test is significant

Option A. : Yes , the overall ANOVA was significant and there are more than two groups.
