You're doing an experiment to test whether students fed a new element, "brainium", will do better on tests. 50 students are fed 250 mg of brainium everyday for a week, and 50 students are fed 250 mg of a placebo (something that looks like brainium, but isn't) everyday for a week. After the week of treatment all students are given the same test. What is the dependent variable? Select the best answer. The students. The amount (250 mg). Time. The test scores. The type of pill (brainium or placebo) The 50 students fed the brainium. The 50 students fed the placebo.
