yes all experiments need to have a control
The control group gives you something to compare the results to.
The control group in an experiment is the group that nothing is done to. The reason why there is a control group in experiments is to compare it with the group that has been tested.
This would be 'the control group' which experiments are compared to.
A control group is the normal condition of whatever it is we're experimenting on, and we use them to see if the experiment is doing what we want it to.

control group & variable
Experiments typically use control groups. One group of people are manipulated and measured, while the control group just stays as they are. The control group is measured against the manipulated group to see what changes.

A control group is a few items that are used as a base to compare results. They are neutral and generally used in scientific experiments.
In a scientific study, the control group is a set of subjects that does not receive the treatment being studied, used for comparison to evaluate the effectiveness of the treatment on the experimental group.
Experiments that test to see if dogs are color blind must use a control group. Otherwise, the results are inaccurate and not scientifically valid.
control group
When doing experiments you have to have a control group and an experimental group. The control group is not given a drug (for example), while the experimental group is. This will show (later on) if the drug had a real effect. Sometimes the control group will be given what is called a placebo. This looks just like the drug that the experimental group is given, except it has nothing in it.
