Which follow-up procedure you use? Why?

We used Pair-wise comparison for the follow procedure to determine which pairs are significantly different for the following reasons:

  • Main effect has more than 2 groups (disability of child), and
  • The main effect was disability status of child was significant

However, with more than 2 groups, you will need to conduct pair-wise comparisons within each IV to determine which pairs are significantly different.

Write a Results section reporting the results of the analysis.
