What is an independent variable?

Back

An independent variable is the variable that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured and affected in an experiment, depending on the independent variable.

In the equation m = d, which variable is independent?

Back

d (distance) is the independent variable.

In the equation m = d, which variable is dependent?

Back

m (amount of money raised) is the dependent variable.

Front

What does it mean when we say 'the more hours Dalton babysits, the more money he earns'?

Back

It means that the amount of money earned (dependent variable) increases as the number of hours babysat (independent variable) increases.

Front

If the number of students in a class increases, what happens to the number of treats Sarah brings?

Back

The number of treats (dependent variable) increases as the number of students (independent variable) increases.

Front

What is the relationship between independent and dependent variables?

Back

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