Question
A researcher used ANOVA and computed an F ratio for the above data. A. If the mena for treatment III were changed to M=25, what would happen to the size of the F ratio (increase or decrease) Explain. B. If the SS for the treatment I were changed to SS=1400 , what would happen to the size of the F ratio (increase or decrease) Explain.
Treatments n=10 n=10 n=10 M=20 M=28 M=35 SS=105 SS=191 SS=180Explanation / Answer
A. If the mean for treatment III were changed to M=25, what would happen to the size of the F ratio (increase or decrease) Explaina. If the mean for treatment III were changed to M=25, what would happen to the size of the F ratio (increase or decrease) Explain
Ans:
If the mean for treatment III were changed to M=25 ,it would reduce the size of the mean difference .This would reduce the size of MS between and would reduce the size of the F ratio
B. If the SS for treatment I were changed to SS =1400, what would happen to the size of the F ratio (increase or decrease)
Ans:
If the mean for treatment Iwere changed to SS=1400 ,it would increase the size of thevariability within treatments .This would increase MS within and would reduce the size of the F ratio
