If you don't have control variables, your conclusion won't be accurate. Say you're studying cats and you give calico cats fancy feast, and Siamese cats science diet dry food. If the calico ones have a larger appetite, you can't tell if it's because cats prefer fancy feast, calicoes prefer fancy feast, or if calicoes just have larger appetites.
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 dependant variable
The Variables That do not change in the experiment
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
Control Variable
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.
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, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.
It is easier to control independent variables
the dependant variable
The Variables That do not change in the experiment
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.

So that you can know what is the manipulating variable, the controlling variable, and the responding variable! To control the variables!
You need to control the variables because if you have two or more variables in an experiment you will never know which variable caused a change or not caused a change.
