Problem
You want to examine how Delanex (a new SSRI) interacts with different liquids. So you set up a study to examine 10mg and 20mg of Delanex along with a placebo control group. You also look at water, gratefruit juice, and whole milk as the liquids. Your dependent variable is depression.
a) What kind of analysis will you do?
b) What are your independent variables (be sure to list out all the levels of each).
