Textbook Problem

An independent-measures study comparing four treatment conditions with a sample of *n* = 8 in each condition produces sample means of *M*_{1} *=* 2. *M _{2}* = 3. M

a. Compute SS for the set of 4 treatment means. (Treat the means as a set of *n* = 4 scores and compute *SS*.)

b. Using the result from part a. compute *n*(*SS*_{mean}). Note that this value is equal to *SS*_{between} (see Equation 12.6).

c. Now, find the 4 treatment totals and compute *SS*_{between} with the computational formula using the *T* values (see Equation 12.7). You should obtain the same result as in part b.

**a.**

To determine

**To find:** SS for the set of 4 treatment means.

Explanation

**Given info:**

A study comparing 4 treatment conditions each with 8 sample size produce means of 2, 3, 1, 6 respectively.

**Calculation:**

*The formula of SS for the set of 4 treatment means is:*

Here,
