A control sample or control group is used to compare with the experimental group or sample. The control sample ideally, should be exactly the same as the experimental sample except that you don't give your experimental treatment to the control sample. Afterwards you compare the 2 samples to see if your experimental treatment had any kind of effect. The control is like a reference point.
control means to take conrol in a science experiment
Control in a science experiment means it stays the same and you don't do anything to it.
Controlling a variable in an experiment means keeping it constant or changing it deliberately to see how it affects the outcome. This helps to isolate the effects of that specific variable on the results of the experiment.
a control is something that stays the same in an 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.
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 is the unaffected group in a science experiment.
a control group assures that an experiment will be repeatable
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, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
