What is the dependent variable?
the more time david spent playing video games, the lower his grades became.

a) number of video games owned
b) points earned playing video games
c) david's time playing video games
d) david's grades

Dear Foxqueen, the dependent variable is D because the grades depend on the time spent playing video games. A is not logical because the video games owned might not be played, B is illogical because the points are the product of the video games, and C is not logical because that is actually the independent variable. (rate this brainiest)

Not sure what the question is?
