Pair-wise Comparisons for ANOVA – Learn It 3

  • Complete pair-wise comparisons for ANOVA
  • Calculate a confidence interval and p-value for pair-wise comparisons and explain what it means

Scenario: Suppose you are studying the efficacy of new statistics teaching methods. You randomly assign [latex]20[/latex] students to each of the four different methods: [latex]A[/latex], [latex]B[/latex], [latex]C[/latex], and [latex]D[/latex]. You test their knowledge on the midterm to compare the differences between the teaching methods. For this activity, you may assume the conditions for ANOVA are met.

We could continue and conduct all six different hypothesis tests/confidence intervals in order to determine exactly which means are different from one another.
