If a student wants to know if studying longer improves test scores, what is the dependent variable?

The test scores.

Front

What does it mean to control a variable in an experiment?

Back

Controlling a variable means keeping it constant to ensure that any changes in the dependent variable are due to the independent variable.

Front

Why is it important to identify independent and dependent variables in an experiment?

Back

Identifying these variables helps to clarify the relationship being tested and ensures that the experiment is designed correctly.

Front

In the statement 'The more hours you study, the higher your test score will be,' what is the independent variable?

Back

In the statement 'The amount of rainfall affects the growth of crops,' what is the dependent variable?
