a. True

b.False

9. A research report states that there are “significant differences between treatmens with F(2,27)=5.36, p<.05.” Based on this report, you can conclude that the research study evaluated the mean differences for three treatment conditions.

a. true

b. false

a. true

b. false

THANK YOU SOOOOO MUCH IN ADVANCE :)

Explanation / Answer

1) SSwithin , MSwithin , SStotal all are we calculate in analysis of variance.

MStotal we are not calculated in analysis of variance.

So correct option is c. MStotal

2) F-ratio with df = 2 , 36

So individual participants are 2 + 36 + 1 = 39

So correct option is a. 39
