The following values are from an independentmeasures study c

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

            conditions.

                                         Treatment

                        I                       II                      III

                        n=10                n=10                n=10

                        SS=1005         SS=1391         SS=1180

            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.
