4.8 Practice 6th- Independent vs. Dependent Variables

Front

What is an independent variable?

Back

What is a dependent variable?

Back

A dependent variable is a variable that is measured and affected in an experiment. It depends on the independent variable.

Front

In the relationship between hours worked (h) and money earned (m), which is the independent variable?

The independent variable is h (hours worked).

Front

What is the purpose of identifying independent and dependent variables in an experiment?

Back

Identifying independent and dependent variables helps to understand the relationship between them and how changes in one affect the other.
