Question

1.The results of testing the significance of a main effect of Factor A in the two-factor ANOVA for independent samples are reported as F(1, 19) = 5.00. Based on this result, the correct conclusion is (assume p < .05). A. reject null hypothesis and conclude that there is an evidence of significant effect of Factor A. B. reject null hypothesis and conclude that there is no evidence of significant effect of Factor A. C. fail to reject null hypothesis and conclude that there is evidence of significant effect of Factor A. D. fail to reject null hypothesis and conclude that there is no evidence of significant effect of Factor A. E. None of the above.
2.For a research study with 2 levels of factor A, 2 levels of factor B, and n = 15 in each treatment condition, what are the df values for the F-ratio evaluating the main effect for factor A?
A. 3, 50 B. 2, 39 C. 1, 56 D. None of the above.

Explanation / Answer

1)here as p value for above test is significant (as p <0.05); option A is correct

2)

for main effect of A ; degree of freedom =levels of A-1=2-1=1

and df for errors=ab(n-1)=2*2*(15-1)=56

hence option C is correct
