I can best explain through example. Let's say that you are sea sick. You take two remedies, an acupressure bracelet and 50 milligrams of meclizine. You quickly start to feel better, but which of the two factors made the difference? The bracelet? The meclizine? A combination of both? This is a small-scale example, but in the fields of science it becomes important to know what causes a certain affect. This is the reason that we use controls.-Akilae

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.
What is a purpose of the control bottle in the model?
This question doesn't make much sense - what model and what bottle? A control is usually something in an experiment that you don't change, just to show what the normal reaction will be.
Why is it important to control an experiment?
The control experiment allows a standard of comparison for the experimental group
What do you call something you experiment on?
Control and Experiment group is what you would normally have in an experiment
In an experiment there are two groups. Which group is not changed in any way?
the control.constantif you make no changes, then its not called an experiment...The control is variable
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.
In an experiment what is the purpose of ta control?
The control group stays the same throughout the entire 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 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
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.
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.
The factor in an experiment that is changed on purpose?
the factor an experiment that is changed on purpose
What is purpose of doing an experiment?
the purpose of doing an experiment is to discover new things
