As the number of credit hours a student takes in a semester increases, the amount of tuition, access fees, and the number of student loans available also increase. Which of the following is the independent variable?

Rationale

The independent variable is the number of credit hours a student takes in a semester.

The independent variable is the variable that is manipulated or changed in an experiment or study, and it directly affects the dependent variables. In this scenario, the number of credit hours is the variable being manipulated or changed, which then influences the amount of tuition, access fees, and the number of student loans available.

A (Amount of tuition) YOUR ANSWER

The amount of tuition is not the independent variable because it is directly influenced by the number of credit hours a student takes. As the number of credit hours increases, so does the amount of tuition. Therefore, the amount of tuition is a dependent variable in this scenario.

B (Number of credit hours) CORRECT

The number of credit hours a student takes in a semester is the independent variable. This is because it is the variable that is being manipulated or changed, which then affects the dependent variables: the amount of tuition, access fees, and the number of student loans available.

C (Number of student loans available) YOUR ANSWER

The number of student loans available is not the independent variable because it is affected by the number of credit hours a student takes. As the number of credit hours increases, the number of student loans available may also increase. Hence, the number of student loans available is a dependent variable.

D (Amount of access fees) YOUR ANSWER

The amount of access fees is not the independent variable because it is influenced by the number of credit hours a student takes. As the number of credit hours increases, so does the amount of access fees. Therefore, the amount of access fees is a dependent variable in this scenario.

Conclusion

In a study or experiment, the independent variable is the one that is manipulated or changed, and it directly impacts the dependent variables. In this scenario, the number of credit hours a student takes in a semester is the independent variable because it affects the amount of tuition, access fees, and the number of student loans available. All other variables mentioned are dependent variables as they are influenced by the number of credit hours.

As the number of credit hours a student takes in a semester increases, the amount of tuition, access fees, and the number of student loans available also increase. Which of the following is the independent variable?

The independent variable is the number of credit hours a student takes in a semester.
