An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
I'm on the same question, I need help
i have no idea im doing this too
The independent variable is the variable that is manipulated or controlled in an experiment, while the dependent variable is the variable that is measured or observed and is affected by the independent variable.
In this case, the independent variable is the "Time Worked (hours)" because that is the variable that is being manipulated or controlled by Chris. Chris decides how many hours to work each week.
On the other hand, the dependent variable is the "Money Earned" because that is the variable that is being measured or observed and is influenced by the independent variable. The amount of money Chris earns depends on the number of hours he works.
Therefore, the correct answer is D) The dependent variable is money made, and the independent variable is hours.
