How do you identify the independent variable in a scenario?

Back

The independent variable is usually the one that you can change or control, and it is often plotted on the x-axis of a graph.

How do you identify the dependent variable in a scenario?

Back

The dependent variable is what you measure in the experiment and is affected by the independent variable; it is often plotted on the y-axis.
