It is so that the experiment is a fair test.
In order to protect the integrity and / or accuracy of the experiment and its results, you have to be able to control all the variables so that you know exactly why something is happening. If you do not control the variables, then one of them could be the reason for the results, and you won't be sure why you got the results you did.
It's important to control your experiment so that you can be sure the results are due to the experimental variable (independent variable) and not something else.
So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
The variable that is kept constant in an experiment is called the control variable. It is important to keep this variable consistent so that any changes in the outcome of the experiment can be attributed to the variable being tested.
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
control is when nothing is done to the experiment and controlled variable is that you have control over the experiment.
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
The control is whatever you base your experiment on. No control = you can't compare your data to anything = good luck making sense out of your experiment. You aren't following the scientific method if there is no control.
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 is the standard to which an outcome of an experiment is compared, but a variable is something in an experiment that can change.
