a. Power
b. The effect size
c. The significance level
d. How normal the distribution is
You know your research hypothesis must be correct.But you want to know if your experiment is likely to succeed in establishing statistical significance.What must you consider?
a. Power
b. Effect size
c. The significance level
d. How normal the distribution is
What are examples of marginal means?

b. The frequencies in each cell of a Chi Square
c. The means of means (or collapsed means) in a Factorial ANOVA
d. The variables used in carrying out your test
In which of these tests do you look at the distribution of frequencies for two independent variables?
a. Factorial ANOVA
b. Two-way ANOVA
