Answer the following questions using the APA format. Provide peer review reference (s)

1) ANOVA can handle 2+ group differences. When there are only two groups, the findings are mathematically similar. But when 3+ groupings are involved we need to run a post hoc test, such as a Tukey HSD test–why is that and provide an example?

2) Why does ANOVA fall under the category of parametric analysis methods? Provide an example.

3) What is the significant of the (continuous) DV one-way ANOVA? Provide an example.

4) Why does the df indicate how much independent information goes into the parameter estimate? Provide an example.
