What is an experimental group and why is it important?
An experimental group is
the group in an experiment that receives the variable being tested
. One variable is tested at a time. The experimental group is compared to a control group, which does not receive the test variable. In this way, experimental groups are used to find answers in an experiment.
What is control group example?
A simple example of a control group can be seen in an experiment in which
the researcher tests whether or not a new fertilizer has an effect on plant growth

enables the experimental study of one variable at a time
, and it is an essential part of the scientific method.
Why is having a control group important?
A control group is an essential part of an experiment
because it allows you to eliminate and isolate these variables
. Control groups are particularly important in social sciences, such as psychology.
