• The use of words to describe what is observed in an experiment.

• The analysis of statistical data to draw conclusions.

• The collection of data through surveys and questionnaires.

Independent Variable

• The factor that is changed by the investigator to observe how it affects a dependent variable.

• A variable that remains constant throughout the experiment.

• The outcome that is measured in an experiment.

• An untestable theory about the universe.

• A random guess without any basis.

Control
