The variable in an experiment deliberately changed by the scientist. The variable being tested.

• dependent variable
• independent variable
• data
• control group

If you were testing how well different dish soaps cleaned grease, the independent variable would be the:

• dish type
• amount of grease
• dish soap type
• grease type

The variable that depends on changes to the independent variable. 

• control group
• dependent variable
• experimental variable
• independent variable
