Because you need to see what differs after you test it.
You need to be able to make comparisons between the result and the original.

Why is a control set in a experiment so important?
When performing an experiment it is very important to have a control set. It is important to have a control set because it ensures that the experiment can be repeated as many times as necessary.
What is an experiment with the variable left out?
A control experiment with respect to that variable. There may be several variables and it may be necessary to leave each one of them out in a different control.
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.
Are controls always necessary in an experiment?
Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
Why is a control group necessary in the scientific experiment?
Without the control group, the test is not able to measure the difference with a standard condition

Why is control setup necessary in an experiment?
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?

In an experiment there are two groups. Which group is not changed in any way?
the control.constantif you make no changes, then its not called an experiment...The control is variable
Does your science experiment have to have a control?
Yes, any science experiment needs a control, or else you don't have a baseline from which to base your understanding of the rest of your data.
What is the role of a control group in any experiment?
To compare data
Why is it inportant to control variables in a experiment?
Because if you have any unknown factors you wont know how the experiment will react in any given situation.
Do you need to have a control for an experiment on which place is the dirtiest in the house?
You need a control for any experiment. It doesn't sound like this particular experiment is of the utmost importance but it's a good habit to get into if you plan more important ones. I have no idea what the control would be.
Why is it necessary to have an independent variable that is changed by the experimenter during an experiment?
The independent variable is changed by the experimenter so that the results can be compared to the control, which does not change. Any differences between the control and experimental group are due to the independent variable. cw: As written, you don't.
