    Positive control

    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.

    Negative control

    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.

    如果簡單的作個分別

    陽性控制--加強它的表現

    陰性控制--抑制它的表現
