Question

Steve plots a line graph for the student population from grade 1 to grade 5 as shown below.
What is the dependent variable?

• A. Student population
• B. Grade
• C. Both student population and grade
• D. Neither student population nor grade

Answer 1

The correct option is A Student population

The dependent variable is the one whose value changes as a
result of changes in the independent variable.

Moreover, the independent variable belongs on the x-axis (horizontal line) of the graph, while the dependent variable belongs on the y-axis (vertical line).

Thus, while plotting student population vs grade, the student population is the dependent variable.
