If an analysis of variance is used for the following data,what would be the effect of changing the value of M₂ to 25? Sample Data $$\begin{array} { l l } M _ { 1 } = 10 & M _ { 2 } = 20 \ S S _ { 1 } = 90 & S S _ { 2 } = 70 \end{array}$$ A)Increase $S S _ { \text {between } }$ and increase the F-ratio B)Increase $S S _ { \text {between } }$ and decrease the F-ratio C)Decrease $S S _ { \text {between } }$ and increase the F-ratio D)Decrease $S S _ { \text {between } }$ and decrease the F-ratio

Changing the value of M₂ to 25 will increase the difference between the two sample means, thus increasing the numerator of the F-ratio (which is SS_between) and therefore increasing the F-ratio.
