Jack conducts an experiment to see whether fear makes mice run through mazes faster. He first selected a sample of 60 mice and then divided them into a control group and an experimental group. He plays a loud sound for the experimental group and induces fear into them. He noticed that the control group mice were running faster. He discovers that someone left a piece of cheese accidently at the end of the maze for the control group which should not have been there. What is the independent variable from the study above?

Ответ:
The independent variable is the loud sound.
Explanation:
An independent variable is the variable that is purposefully changed or controlled in an experiment. The piece of cheese was not purposefully left there and is not the independent variable.
