To have something to compare the rest of the experiment to
Everything except what you're measuring. EXAMPLE: In a biological experiment using specially treated cells the experiment is run with the cells; this is the experiment. Then the experiment is run again with the same cells WITHOUT the special treatment; this is the control.
A control setup is something where you know how it will behave. It gives you a reference to measure affect of all other variables.
were you setup your own experiment
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
A positive control is used in an experiment to ensure that the experimental conditions are capable of producing a positive result. It helps validate the experimental setup and serves as a reference point for comparison with the test samples.
A control group is used to separate the setup for an experiment from the surroundings by providing a baseline for comparison. It is a group that is exposed to the same conditions as the experimental group but does not receive the treatment being tested. This allows researchers to determine the specific effects of the treatment being studied.
