Explanation:

A dependent variable is what is being measured and is affected by the independent variable. Here, the number of mosquito - bites is being counted and is likely affected by the presence or absence of mosquito repellent. The independent variable is the application of mosquito repellent (sprayed on one arm, not on the other), and the number of bites depends on this application.

The number of mosquito bites after two hours.
