What is the difference between planned comparisons and post hoc tests?
Homework Answers
In a post-hoc test which is used for situations where we can decide which comparisons we want to make after we get the data by looking at the data.
In planned comparison tests we require that we focus on doing sensible comparisons in a scientific way. The choice must be based on the scientific questions we ask, and this should be chosen when we design the experiment.

In a One-Way ANOVA, it is essential to do Post-Hoc analyses (comparisons) because Group of answer choices a. The Post Hoc tells us if there is a significance between “all groups combined” while the F ratio tells us where only one difference is. b. The F ratio only tells us there is a significance between “all groups” and the Post Hoc comparisons show us where that difference is in each “pair” of groups. c. The F ratio tells us if...

QUESTION 1 After a one-way ANOVA test, you conduct all possible post-hoc pairwise comparisons using the Bonferroni correction. If there were 4 groups (J = 4), what would your adjusted alpha value be for the post-hoc tests? Remember, our alpha is 0.05 for the class. Round final answers to four decimal places.
