If an analysis of variance is used for the following data, what would be the effect of changing the value of M 2 to 25?Sample Data M1 = 10 M2 = 20 SS1 = 90 SS2 = 70 a.an increase in SSbetween and an increase in the F-ratio b.a decrease in SSbetween and a decrease in the F-ratio c.an increase in SSbetween and a decrease in the F-ratio d.a decrease in SSbetween and an increase in the F-ratio

F-ratio is interpreted as the ratio of mean sum of squares between and mean sum of squares within. The formula for F ratio is as follow:If the mean of one group will increase then the mean sum of squares between the group will also increase. Therefore, the effect of changing the value of M2 to 25 makes an increase in SSbetween and an increase in the F-ratio. Thus, the correct option is a).
