Answer 1

The dependent variable in the experiment is the number of students sleeping.

Step-by-step explanation:

A dependent variable is what is being studied and measured in the experiment. In contrast, the indpendent variable is the thing that is changed that can alter the dependent variable. In the experiment the indpendent variable is the brightness of the lights. The brightness of the lights can alter how many students sleep in his class.
