He needed a control group. *Apex*
A control group is the unaffected group in a science experiment.
To accurately identify the control group for the experiment, more context about the specific experiment is needed, including its objectives, methodology, and the variables being tested. Generally, a control group is a baseline group that does not receive the experimental treatment or intervention, allowing researchers to compare the outcomes with those of the experimental group that does receive the treatment. If you provide more details about the experiment, I can give a more precise answer.
a control group assures that an experiment will be repeatable
the group that does not change in the experiment VIVI :)
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.
control group
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)

The control group stays the same throughout the entire experiment.
A control group creates a 'yard-stick' to measure any changes in the experiment. For example, suppose you're testing a new diet pill on 100 people - you'd only give the pill to half the group, leaving the other half as a 'control' to see if the diet pill actually works.
