# ANOVA: Sum of Suares

Please show the work.

The following data represent the results from an independent-measures study comparing three treatments.

a. Compute SS for the set of 3 treatment means.

(Use the three means as a set of n = 3 scores and

compute SS.)

b. Using the result from part a, compute n(SSmeans).

Note that this value is equal to SSbetween (see

Equation 13.6).

c. Now, compute SS between with the computational

formula using the T values (Equation 13.7). You

should obtain the same result as in part b.
