Negative Control
A control method originating in experimental science, in which a control group known not to produce the expected effect is set up to verify whether the detection system itself has failed.
Timeline (last 90 days)
Negative controls originate from experimental science and are used to confirm that the detection system itself has not failed.
The positive control is borrowed from experimental science and means testing a known necessarily positive control sample before testing the sample to prove the detection process works; the negative control confirms that records that should not be returned do not appear; neither carries information about the time dimension.
Negative controls require deliberately including inputs on which the system should fail or score low; if the metric passes them, the metric is broken rather than the system being good.
