Dependent and Independent Variable Review

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured or tested in an experiment. It depends on the independent variable.

Front

What is an independent variable?

Back

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

Front

On which axis is the dependent variable plotted on a graph?

Back

The dependent variable is plotted on the y-axis.

Front

On which axis is the independent variable plotted on a graph?

Back

The independent variable is plotted on the x-axis.

Front

What does it mean if a graph shows a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also increases.

Front

What does it mean if a graph shows a negative correlation?

Back

A negative correlation means that as one variable increases, the other variable decreases.

Front

In the equation y = mx + b, what does y represent?

Back

In the equation, y represents the dependent variable.

Front

In the equation y = mx + b, what does x represent?

Back

In the equation, x represents the independent variable.

Front

What is the purpose of a control variable in an experiment?

Back

A control variable is kept constant to ensure that the results are due to the independent variable.

Front

How can you identify the dependent variable in a word problem?

Back

The dependent variable is usually the outcome or result that is being measured.
