A researcher investigated the relationship between alcohol intake and reaction time using a driving simulation task. Participants drank either one ounce or three ounces of alcohol. Their reaction time was measured in terms of the speed with which they braked on seeing a red light during the simulated driving task. In this case, the dependent variable in the experiment is the _____.

Question

Quizplus · Accepted Answer

The dependent variable in the experiment is the reaction time measured in terms of the speed with which they braked on seeing a red light during the simulated driving task, which is indicated by the braking speed. The amount of alcohol is the independent variable, and the red light and degree of intoxication are not directly measured or manipulated in this experiment.
