Answer 2

Is this a statistics problem?

Answer 3

i dunno.

Answer 4

An independent variable is a variable that stands alone and is not changed by any other variables. A dependent variable depends on other factors.
For example:

(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).

Answer 5

A dependent variable is the variable being tested in a scientific experiment.
An independent variable is the variable that is changed in your scientific experiment to test the effects on the dependent variable.

You can eliminate B and D because they refer to the age of the people and we are talking about the relationship between the amount of caffeine consumed during the day and the time required to fall asleep at night.
