A positive control is a group in an experiment that receives a treatment with a known result, and therefore should show a particular change during the experiment. It is used to control for unknown variables during the experiment and to give the scientist something to compare with the test group.
What is an example of a negative control?
A negative control may be a population that receive no treatment. That is to say that an independent variable is set to nothing. For example, an experiment for a snowboard wax is designed to see if the wax improves the speed of snowboarders in race conditions.
