Question

Quizplus · Accepted Answer

The number of hours slept the night before the driving test is not related to the use of cell phones while driving, and therefore it is an extraneous variable that can potentially affect the results of the study. The independent variable is the use of cell phones while driving, and the dependent variable is the likelihood of having an accident. A control variable would be a variable that is deliberately kept constant in the study to reduce the impact of extraneous variables, but the number of hours slept is not a control variable in this case.
