Question

In an experiment, what is the purpose of the control group?

Answer 1

A control group is the comparison group that helps to "make sure your experiment works." A control group is separated from the rest of the experiment and nothing happens to it kinda like a controlled variable.  Controlled variables are the variables in a experiment that remains the same for example a temperature, time, type of products, etc..

Hope this helps!
