Answer 1

Tom is studying how changes in income affect the frequency of eating out. In this example, "changes in income" is the independent variable and "frequency of eating out" is the dependent variable.

 

The independent and dependent variable are the two main variables in an experiment. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. The element being tried out and measured in a scientific experiment is the dependent variable.
