Sum of Squares A key calculation in ANOVA used to measure variation. summary of the formulas for these topics, or do you need help with a specific problem from the DVD? This concept is notoriously difficult for students because

"The paired difference test in my textbook took up 10 confusing pages. The DVD covered it in 45 minutes. I finally understood why we subtract the columns. Worth every penny." Hypothesis Testing with Two Variances: Determines if there
