  • MSwg

    SSwg/df (N-K)
  • MS used in denominator for between groups ANOVA
    MS within
  • MS used in denominator for repeated measures ANOVA

    MS residual
  • Statistical interaction

    An F-test can be conducted in place of a T-test when only two groups are being compared. (T2 = F)
  • Null hypothesis in ANOVA (Ho)

    All group means are equal (no differences)
  • Alternative hypothesis in ANOVA (H1)
    At least 2 group means are unequal (there is at least one difference)
  • Post-hoc tests are conducted after conducting an overall ANOVA F-test (reveals that the null hypothesis should be rejected) and when there are more than 2 groups being compared
  • The expected value of F under the null hypothesis is 1
