Question: 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*SS_Means .Note that this value is equal to SS_between (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.
