Dr. Hines is interested in studying how indoor lighting can influence people's moods during the winter. A sample of 100 househol
ds 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.
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 <em>depends</em> 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.
