Question

read the scenario. what is the dependent variable? scenario: the johnson family has decided to try to save electricity (and money at the same time). they were told that they could replace their regular light bulbs with special fluorescent bulbs that use less energy. they wonder if it is really worth doing in order to save electricity usage.

Explanation:

In an experiment, the dependent variable (DV) is what is being measured or observed and depends on the independent variable. Here, the Johnson family is testing if replacing bulbs affects electricity usage. So electricity usage is what's being measured (depends on bulb type), making it the DV.

Answer:

Electricity usage
