What is the experimental group? on edpuzzle

An experimental group is a test sample or the group that receives an experimental procedure.

Explanation: This group is exposed to changes in the independent variable being tested. The values of the independent variable and the impact on the dependent variable are recorded. An experiment may include multiple experimental groups at one time.

Hope this helps! :)

there are two significant figures.
