  1. One Way ANOVA • One Way ANOVA’s involve a single independent variable

  2. Logic for ANOVA • The logic for an F-test (ANOVA) is the same as other hypotheses tests • The MSBetweenexpected is always believed to be zero

  3. Calculating Sum of Squares • These are the formulas for the variance partitions

  4. Calculating df and MS • dfbet= No. of Groups – 1 = k-1 • dfwith = No. of Subjects – No. of groups = N-k • dftot = No. of Subjects – 1 = N-1
