Question

Quizplus · Accepted Answer

The duration of food deprivation is being manipulated by the researchers and is therefore the independent variable. The dependent variable is the time it takes for the rats to complete the maze, which may be affected by the level of food deprivation. The rats are not a variable in this case as they are being used as subjects in the study.
