test variable you change
control you don'tWhat is a test variable and a controlled variable?
The test variable is the one that you are interested in and the controll is just to measure what happens when nothing changes. For example A test to see if a new medicine works. The test variable would be the actuall medicine, while the controll would be a fake (like a sugar pill) that would do nothing. After some time we check up on the patients and see if there is a difference between the test and control. If the patients with the real medicine got better then our new drug is a success!
