On which axis is the independent variable typically plotted on a graph?

Back

The independent variable is typically plotted on the x-axis.

Back

The dependent variable is typically plotted on the y-axis.

Front

If you increase the number of hours worked, what happens to the money earned?

Back

The money earned (dependent variable) increases as the number of hours worked (independent variable) increases.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.

Back

The independent variable is the study time.

In a study measuring the effect of study time on test scores, what is the dependent variable?

Back

The dependent variable is the test scores.
