control and experimental setup
were you setup your own experiment
To have something to compare the rest of the experiment to
In a properly designed experiment, it is important to have at least 2 controlled variables. With two variables you are able to remove one at a time and see the effect in your setup.
A control setup is something where you know how it will behave. It gives you a reference to measure affect of all other variables.
A variable in science is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by a scientist in the experiment. The depended variable is what you measure in the experiment and what is affected during the experiment. A controlled variable is one which the researcher holds constant (controls) during an experiment.
were you setup your own experiment
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?

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.
