What are the results of two way mixed ANOVA?

Which is the main effect of a mixed model?
A main effect is the effect of a particular independent variable, averaging across all levels of the other independent variable(s).

What are the results of a 2×2 repeated measures ANOVA?
The results from a 2×2 repeated measures ANOVA are the same as you would get if you used paired-samples (t)-tests for the main effects and interactions. Back to top 9.4: Knowing what you want to find out
Are there any outliers in the two way ANOVA?
The problem with outliers is that they can have a negative effect on the two-way ANOVA, reducing the accuracy of your results. Fortunately, when using SPSS Statistics to run a two-way ANOVA on your data, you can easily detect possible outliers.
