If Sarah brings 2 treats for each student, what is the relationship between treats and students?

Back

The number of treats (t) depends on the number of students (s), making treats the dependent variable.

If you increase the number of boxes sold, what happens to the money collected?

Back

The money collected is likely to increase, making it the dependent variable.

Front

In a scientific experiment, why is it important to identify independent and dependent variables?

Back

Identifying these variables helps to understand the cause-and-effect relationship in the experiment.
