The following data were obtained from an independentmeasures study comparing three treatment conditions.

a. Calculate the sample variance for each of the three samples.

b. Use an ANOVA with a 5 .05 to determine whether there are any significant differences among the three treatment means. (Note: In the ANOVA you should find that MS_within
is equal to the average of the three sample variances.)
