What is the purpose of a hypothesis in an experiment?

Back

A hypothesis is a testable statement that predicts the relationship between the independent and dependent variables.

What does it mean to control variables in an experiment?

Back

Controlling variables means keeping all other factors constant except for the independent variable to ensure that any changes in the dependent variable are due to the manipulation of the independent variable.

What is the role of a control group in an experiment?

Back

A control group is a standard of comparison that is not exposed to the independent variable, allowing researchers to see the effect of the independent variable.
