The following values are from an independent-measures study comparing three treatment conditions.

a. Compute the variance for each sample.

b. Compute MS_within, which would be the denominator of the F-ratio for an ANOVA.

Because the samples are all the same size, you should find that MS_within
is equal to the average of the three sample variances.
