Identifying Variables

Identifying Variables

A science experiment has three kinds of variables.

• Independent variable – The factor that changes in an experiment

• Dependent variable – What is being measured in an experiment

• Control variable – The factor that remains constant in an experiment

Identify the three variables in the following scenarios

Two groups of fifth graders were tested to compare their speed solving long division problems. One group had calculators, the other didn’t.

What is the dependent variable?
