# Dependent and independent variables review

CCSS Math: 6.EE.C.9

Identify dependent and independent variables and apply them to contexts.

## Independent variable

An

**independent variable**is a variable that represents a quantity that is being manipulated in an experiment.$x$ is often the variable used to represent the independent variable in an equation.

### Example:

You are doing chores to earn your allowance. For each chore you do, you earn $\$3$.

**What is the independent variable?**

The independent variable is the amount of chores you do because this is the variable you have control over.

## Dependent variables

A

**dependent variable**represents a quantity whose value*depends*on how the independent variable is manipulated.$y$ is often the variable used to represent the dependent variable in an equation.

### Example:

Let's use the same context.

You are doing chores to earn your allowance. For each chore you do, you earn $\$3$.

**What is the dependent variable?**

The dependent variable is the amount of money you earn because the amount of money you earn

*depends*on how many chores you do.*Want to learn more about independent and dependent variables? Check out this video.*
