What is the role of controls in the scientific process?
The control is there to compare the difference between it and the experiment. It should not change, but will be affected by the same environmental influences. By checking the control you can rule out environmental influences that may also have affected your experiment.

What does control mean in an experiment?

A standard of comparison in an experiment is called the?
it is called the control of the experiment
What is the control of a experiment?
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
The standard for comparison in a experiment?
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
What is the control group and what is it used for?
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
What is the definition of control in science?
Control in science is something that can be used for comparison to determine the magnitude of an experimental effect. For example in a control group either nothing is done or a fake version of the experiment is performed to determine a "baseline". The results of the control experiment and the real experiment can be compared. This process helps eliminate the experimenter expectations effect, making the conclusions more objective. Note: controls are rarely needed outside the field of biology.
Why is is it important that an experiment include a control group?
a control group assures that an experiment will be repeatable
Why is it important to control an experiment?
The control experiment allows a standard of comparison for the experimental group
