What is the Dependent Variable?

What is a Control in an experiment?

Back

A standard for comparison that is not exposed to the experimental treatment.

Why is it important to have a control group?

Back

A control group helps to isolate the effects of the independent variable by providing a baseline for comparison.

Front

What is a hypothesis?

Back

A testable prediction about the relationship between two or more variables.

Front

What is the purpose of repeating experiments?

Back

To verify results and ensure that they are reliable and not due to chance.

Front

What is a factor in an experiment?

Back

Any condition or variable that can affect the outcome of the experiment.
