A control group is subjected to the same procedures as the experimental group but does not receive the treatment of the independent variable. In the control group all variables are held constant. It is used as a baseline measure. This helps determine whether any of the resulting effects of the experimental group are due to the independent variable treatment and not to the actions involved in providing the treatment.

Why did mendels use pure lines in his experiment?
He needed a control group. *Apex*
In an experiment a group that is identical to a control group except for one factor and that is compared with the control group?
a controlled experiment is an experiment that tests only one factor at a time by using a control group and experimental group
Why is control important in an experiment?
Every experiment requires a control group. This is so that the group that is manipulated can be compared to a group that has had nothing done to it., in order to measure changes.
The part of an experiment that does not contain the variable is known as?
this group is called the control group. the one that changes is called the variable. as in, it can vary. :) hope this helps!
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.

Why is a control group necessary in a scientific investagation?
A control group is needed to see how the sample responds under normal conditions

He needed a control group.
Why is a control needed in a scientific method?
Because In a scientific method there has to be a independent,controll,and dependent variable. A control group has to be in a scientific method cause ther is only one needed.
Why is a control needed in an experiment?
The control group gives you something to compare the results to. For example, in a medical trial for a new medicine, one group will receive sugar pills. Without this control group, it means nothing if 50% of those treated with the real medicine get better. The control group may have the same results, better results, or worse results. This tells how effective the medicine is. The same is done with any type of experiment.
Why is a control group needed in any experiment?
A control group creates a 'yard-stick' to measure any changes in the experiment. For example, suppose you're testing a new diet pill on 100 people - you'd only give the pill to half the group, leaving the other half as a 'control' to see if the diet pill actually works.
Why should expieriments have a control group?
The control group in an experiment is the group that nothing is done to. The reason why there is a control group in experiments is to compare it with the group that has been tested.
Why do you use a control group?
You use a control group to compare the results of the experimental group to. The control group has the "normal" results. After the experiment, you can tell if and what has changed from the control groups results
What is a control or control group?
the group that does not change in the experiment VIVI :)
What is the control group used for?
