Dr. Hines is interested in studying how indoor lighting can influence people's moods during the winter. A sample of 100 households is selected. Fifty of the homes are randomly assigned to the bright-light condition where Dr. Hines replaces all the lights with 100-watt bulbs. In the other 50 houses, all the lights are changed to 60-watt bulbs. After two months, Dr. Hines measures the level of depression for the people living in the houses. In this example, the level of depression is the variable.

The answer is the dependent variable.

Explanation:

In experimental studies, an independent variable is expected to affect a dependent variable. In this example, the lighting intensity is predicted to influence the participants' mood. This is, their mood depends on the amount of light to which they are exposed.

An easy way to remember the difference is to think: independent causes change in dependent.
