An experiment is performed to test the effect of sleep deprivation on rote memory. In this experiment, the dependent variable is the

ANumber of hours subjects go without sleep

BRote memory scores ✓ Correct

CNumber of subjects deprived of sleep in the experimental group

DCorrelation between hours of sleep and fatigue

Correct answer: (B) Rote memory scores

Explanation

The dependent variable is the rote memory scores, since memory is the outcome measured for change.

Sleep deprivation is the manipulated cause and memory performance is its effect.

The number of hours subjects go without sleep is the independent variable being manipulated.

The number of subjects deprived of sleep in the experimental group is a feature of sample size, not the outcome.

A correlation between hours of sleep and fatigue describes a relationship, not the measured behaviour here.

The dependent variable is always the response recorded to gauge the treatment's effect.
