If an analysis of variance is used for the following data,what would be the effect of changing the value of SS1 to 50?

A)Increase $\text { SSwithin }$ and increase the size of the F-ratio M1 = 10 M2 = 20
B)Increase $\text { SSwithin }$ and decrease the size of the F-ratio SS1 = 90 SS2 = 70
C)Decrease $\text { SSwithin }$ and increase the size of the F-ratio
D)Decrease $\text { SSwithin }$ and decrease the size of the F-ratio

C)Decrease $\text { SSwithin }$ and increase the size of the F-ratio 
D)Decrease $\text { SSwithin }$ and decrease the size of the F-ratio

Quizplus · Accepted Answer

Changing the value of SS₁ to 50 would decrease the value of SSwithin (since SSwithin = SSTotal - SS₁ - SS₂). This decrease in SSwithin would result in an increase in the size of the F-ratio. Therefore, the best choice is C: Decrease SSwithin and increase the size of the F-ratio.
