For Penn State students with specific sleep patterns, controlling time spent on their phones before bed, what is the relationship between time spent on the phone and how long it takes after to fall asleep.

Sample: My sample is Penn State students because it gives me a definable population to target that is a wide audience without including too many people. I specify the need for static sleep patterns so that I can limit variation.

Control Variable: I would be controlling how much time they are allowed to spend on their phones before bed.

Independent Variable: The independent variable would be the time spent on their phones, we could research this based on phone usage data.

Dependent Variable: The dependent variable would be how long it took to fall asleep after turning off their phones. We could research this by giving them surveys to list how much longer it took after setting down the phone to fall asleep.
