The experimental control provides a base-line result or set of results, from which you can compare the variables' effects against. It's designed to minimize the effects of variables (other than the single independent variable). Control groups are often included in medical or psychological experiments so that the results of an experiment are considered reliable and trustworthy.
Example:
A mystery-drug cure is being tested. One group of patients is given the drug and the other group is not. The group without the drug will be subject to all the same conditions that the other group are under, thereby seeking to eliminate any unforeseen effecting environmental factors. This makes it possible to compare, and therefore measure, the impact any drug would have.

What is the purpose of a control group?
The defintion of a control group in an experiment is a standard for comparison. So then the purpose of the whole control group during an expirenment is to have something to compare your data to.
What is the purpose of using multiple control in an experiment?
To help you conclude that no uncontrolled factors significantly influenced your results. To help you determine that your experimental results are valid To help control for factors that aren't being tested but might affect results
In a scientific experiment a control is the part of the experiment that?
remains the same throughout the experiment
What is the purpose of the dry ice bubble experiment?
the purpose is how is is getting bigger
What is the difference between control and experimental variables?
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
In an experiment what is the purpose of ta control?
The control group stays the same throughout the entire experiment.
What is purpose of having a control in a experiment?
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
What is the purpose of the control setup?
To have something to compare the rest of the experiment to
The purpose of blocking in experimental design is?
the control for multiple variables in a experiment
What is the control variable in the experiment is the?
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.
What is the purpose of a control group?
The defintion of a control group in an experiment is a standard for comparison. So then the purpose of the whole control group during an expirenment is to have something to compare your data to.
What is the purpose of a control setup in an experiment?
A control setup is something where you know how it will behave. It gives you a reference to measure affect of all other variables.
What is the purpose of the control group?
The purpose of a control group is to show what would happen under normal conditions. It serves as a comparison to the results you receive from the manipulation of the independent variable on the dependent variable. If a control group is present in an experiment, one can be more certain that the independent variable is really responsible for the observations.
The factor in an experiment that is changed on purpose?
the factor an experiment that is changed on purpose
What is a purpose of a control?
The purpose of a control in any experiment is so that you have a natural example to look at at. Ex: If I was doing an experiment on fertilizer, I'd have three different fertilizers and a plant without fertilizer so I could see how it would grow without fertilizer so I could backtrack if need be.
What is purpose of doing an experiment?
the purpose of doing an experiment is to discover new things
What is the purpose of the airhole in the Bunsen burner experiment?
The purpose is so that you are able to control the amount of air going into the fire changing it from yellow (cooler) to blue (much hotter).
