Front

What is an independent variable?

Back

An independent variable is an amount that can stand on its own and is manipulated in an experiment to observe its effect on a dependent variable.

What is a dependent variable?

Back

A dependent variable is an amount that depends on another amount, often measured in an experiment to see how it changes in response to the independent variable.

Back

It means that the variable can change freely without being affected by other variables.

Front

What does it mean if a variable is dependent?

Back

It means that the variable's value depends on the value of another variable.

In a graph showing distance over time, which variable is typically independent?

Back

Time is typically the independent variable.

Front

In a graph showing cost based on the number of pizzas, which variable is typically dependent?

Back

Cost is typically the dependent variable.

Front

What is the relationship between independent and dependent variables?

Back

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