A control group is an essential part of any experiment because it allows you to reach a reliable conclusion. For example, let's say that you wanted to test out a new diet pill to determine how effective it was. You would need to obtain test subjects and divide them into two groups. The first group would be given the new diet pill while the second group (your control group) would be given a placebo. If at the end of the designated time, the first group lost more weight (a statistically significant amount more) than the control group, you would be able to state conclusively that the pill was effective for weight loss.
In the absence of a control group, it would be unclear whether the cause of the weight loss in your subjects was due to the diet pill or other unrelated factors.
so that it doesn't go out of control
A control group is must for every new experiment or uncommon experiment. Because when an experiment is being done anything unexpected could happen and to control the hazard a control group should be ready everytime. Otherwise it can be very dangerous for the experiment holders. to help you conclude that no uncontrolled factors significantly influenced your results
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...
a control is something that stays the same in an experiment
control means to take conrol in a science experiment
it is called the control of the 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 is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
Control is important in an experiment to eliminate the influence of variables other than the one being tested. By having a control group that is not exposed to the experimental treatment, researchers can accurately gauge the true effect of the independent variable on the outcome. This allows for valid and reliable conclusions to be drawn from the experiment.
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.
a control group assures that an experiment will be repeatable
A control group is the unaffected group in a science experiment.
