Debbie is studying the scientific method in her physical science class. She is working on a science fair project and needs to determine the variables that she will use. Which statement could help Debbie understand the difference between a test variable (independent variable) and an outcome variable (dependent variable)? The outcome variable (dependent variable) is the control and test variable (independent variable) is the result.

The test variable (independent variable) is the result of the changes the researcher makes to the outcome variable (dependent variable). O The test variable (independent variable) is the control and the outcome variable

(dependent variable) provides the results, which are measured to gather data.

The outcome variable (dependent variable) is the result of the changes the researcher makes to the test variable (independent variable).
