Identify the independent variable in the following hypothesis. Children who are given a free breakfast at school perform better on achievement tests and are more motivated for school than are those children who are not given breakfast

Whether or not breakfast is provided

Explanation:

An independent variable is the variable in an experiment that is being changed. The dependent variable, by contrast, changes because of the independent variable.

In this case, children are either given breakfast or they are not. Since the scientists are choosing whether or not to give the children breakfast, that is the independent variable.

Thus, the independent variable is whether or not breakfast is provided.
