PSY 520 Topic 6 Discussion Question 1 and 2

PSY 520 Week 6 Discussion 1: Review the four ANOVA videos in the Calculations section of the Statistics Visual Learner media piece.

Explain the major differences between analyzing a one-way ANOVA versus a two-factor ANOVA, and explain why factorial designs with two or more independent variables (or factors) can become very difficult to interpret.

PSY 520 Week 6 Discussion 2: Explain how the ANOVA technique avoids the problem of the inflated probability of making Type I error that would arise using the alternative method of comparing groups two at a time using the t-test for independent groups.
