The morning before a Biology 1 midterm, half of the students in a class were given plain water for breakfast while the other half were given an energy drink.

What is the independent variable in this study?

In this case, the dependent variable is the grade obtained by every student after drinking the given drink. In this case, the researchers are manipulating which type of drink is to be given to each student. So, the type of drink is the independent variable.
