In the diagram below, there are two data tables. Circle the Independent Variable in each table. HINT: You will circle one thing in each table.

Answer explanation

Be careful when determining the Independent Variable. Remember that the independent variable is the factor that the scientist is controlling or changing. The dependent variable is the result of that change.

Shown below is a data table for an experiment that a student conducted. Which of the following would be considered the dependent variable?

• Plant #

• Days of Growth

• Number of Leaves

Answer explanation

Remember that the dependent variable relies on the independent variable.

Another way to think about this is that the dependent variable is the result(s) of the experiment.
