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.
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.
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 is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
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
Without the control group, the test is not able to measure the difference with a standard condition

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

the control.constantif you make no changes, then its not called an experiment...The control is variable
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.
In an experiment, a control is a baseline or standard against which the experimental group is compared. It ensures that any observed effects can be attributed to the variable being tested rather than other factors. The control group typically undergoes the same conditions as the experimental group, except for the treatment or intervention being studied. This helps to validate the results and enhance the reliability of the conclusions drawn from the experiment.
To compare data
Because if you have any unknown factors you wont know how the experiment will react in any given situation.
It was necessary to degas the sodas prior to the experiment to remove any dissolved gases, such as carbon dioxide, in order to prevent interference with the results of the experiment. Presence of dissolved gases can affect the accuracy of the measurements taken during the experiment.
