Question

Identify the dependent and independent variables on the following scenario:

A researcher is studying the effect of sleep on academic performance, thinking that less sleep will lead to lower grades. She has
some people sleep six hours per night, some people sleep three hours per night, and some people sleep as much as they want.
She then monitors academic behavior during English and math classes among participants. (Site 1)

Answer 1

I think that the dependent variable would be the academic performance because she hypothesizes that the performance depends on how many hours of sleep you get. And the amount of sleep would be the independent variable. I'm not too too sure.

Answer 2

Independent Variable = Effect of Sleep

Dependent Variable = Academic Performance

Explanation:

As we know that dependent variable depends on independent variable and on changing the value of independent variable, value of dependent variable also get changed.

Here in the given scenario academic performance is depend on the effect of sleep. Thus,

Independent Variable = Effect of Sleep ( Number of hours of sleep)

Dependent Variable = Academic Performance.
