A control sample that is known to produce a positive result if the test is working as expected.
Example: printing a test page on a printer with its own driver software to test that it has been installed correctly, before testing the printing behaviour of another piece of software.
A control sample where a negative result is expected, to help correlate a positive result with the variable being tested.
Example: a measurement of background radiation when trying to test the effects of a certain substance on local radiation levels.
