Control Single
In an experiment, why is it important to have a control, and a single variable being tested?

~Thanks!

Control provides you with a reference point to determine what change (if any) occurred when a variable was modified.

If you test more than one variable, you won't know which variable caused the resulting change in the item being tested.
