Question

A psychologist was interested in the effect of hunger on psychological disturbances. She food-deprived half of a group of healthy volunteers for one day and fed the other half normally, then administered a psychological test to all the participants. What was the independent variable?

Answer 1

Answer: Level of food deprivation.

Explanation:

The independent and dependent variables are the fundamental components in an experiment. The independent variable is the controlled one that is modified to examine the consequences it has on the dependent variable. The dependent variable is the one being measured through the scientific experiment.

In this example, the level of food deprivation is the independent variable and psychological disturbances are the dependent variable.
