Detailed explanation-1: -Answer and Explanation: The independent variable is the amount of sleep. The dependent variable is performance on the exam.
Detailed explanation-2: -In an experiment, you change the value of the independent variable to see how it affects the dependent variable. So if you want to see how sleep affects appetite, sleep would be your independent variable and appetite would be your dependent variable.
Detailed explanation-3: -Independent variable causes an effect on the dependent variable. Example: How long you sleep (independent variable) affects your test score (dependent variable).
Detailed explanation-4: -Increasing one’s hours of sleep from say two hours to eight hours might well have resulted in an increase of roughly 20% on a final exam score, which would mean an increase of about 5% in final course average. Such an increase could have resulted in an improvement in grade from a B to an A-.
Detailed explanation-5: -The dependent variable is memory. Memory is tested to determine how sleep deprivation impaired or affected memory.
