If the number of hours studied increases, what happens to the test score?

Back

The test score (dependent variable) is likely to increase as the number of hours studied (independent variable) increases.

What does it mean when we say a variable is controlled?

Back

A controlled variable is one that is kept constant to ensure that the results of an experiment are due to the independent variable.

Give an example of a dependent variable in a science experiment.

Back

An example of a dependent variable is the growth of the plant measured in centimeters.

What is the relationship between independent and dependent variables?

Back

The independent variable is manipulated to observe its effect on the dependent variable.
