Quizplus · Accepted Answer

The dependent variable in this study is the variable that is being measured and is expected to change based on the age group being compared. In this study, time spent sleeping at night is the variable that is being measured, making it the dependent variable. Choice B and C are incorrect because they are not the focus of the study and do not reflect a change that is expected to occur between the two age groups being compared. Choice D is also incorrect because it pertains to a time frame rather than a variable being measured.
