“You want to study the effects of yogurt on children8s math grades. You hypothesize that eating a container of strawberry flavor yogurt every morning will result in higher math test scores.

Which of the following is FALSE?”
“The test scores are the dependent variable, and the types of yogurt are the independent variable”
