because in certain experiments you need an accurate independent variable so your conulsion could be accurate
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.

The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
Controlling for a variable is the act of deliberately varying the experimental conditions in order to take a single variable into account in the prediction of the outcome variable. Controlling tends to reduce the experimental error. A control is something that does not change in the experiment.
The dependent variable is the variable that can change in an experiment.

There is never "only an independent variable". Science and math are both the study of how changes in one thing cause changes in something else. If you can think of something that can change, and NOT have any effect on anything else, then it's an independent variable that can stand alone. But if it has any effect on anything else, then there is always something that depends on it, and that's a DEpendent variable.
Because if you change more than one variable at a time, you can't tell which is affecting the results.

So you can make sure the results you gain are only due to the independent variable and not a variable not being tested.
