1. In analysis of variance, MS between-groups provides a measure of
the total variability for the set of N scores, standard deviation, the overall mean for the set of N scores, differences among treatment means
2. An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this study, the three totals are, T1 = 5, T2 = 10, and T3 = 15. What value would be obtained for the grand mean, Mgrand?
2,10,15,5
Homework Answers
(a) In Anova the MS between groups provides a measure of variance in difference among treatment means.
(2) Grand Mean = (5 + 10 + 15) / 15 = 30 / 15 = 2

A researcher is interested in investigating potential differences in intelligence among members of different sports/activity teams in high school. Specifically, the researcher is interested in differences in intelligence among Chess Team, Soccer Team, and Football Team members. To this end, the researcher gathered intelligence test (IQ) data on a random sample of chess, soccer, and football team members. The data collected for this study reside in the table below. Perform a one-way ANOVA to determine if significant differences in intelligence...
