What is an example of an independent variable?

Back

In a study on plant growth, the amount of sunlight each plant receives is an independent variable.

What is an example of a dependent variable?

Back

In a study on plant growth, the height of the plants is a dependent variable.

Front

Why is it important to have control variables?

Back

Control variables are important to ensure that the experiment is fair and that the results are due to the independent variable.

Front

What happens if you change more than one variable at a time?

Back

If you change more than one variable at a time, it becomes difficult to determine which variable caused the change in the dependent variable.

Front

How can you identify the dependent variable in a question?

Back

The dependent variable is usually the outcome or effect that you are measuring in response to changes in the independent variable.
