Statistical Validity and Significance

A principal of A&I replaces an incorrectly applied model with a proper statistical test to expose flaws in statistical proof of discrimination.

A state ran afoul of a federal audit when, for several months, the customary sample of social workers' time use was not collected due to a transition in the state department.

A Hispanic police officer alleged race discrimination by a Police Department in assignments made to the "Spare List," a list of officers available to cover for other officers out for vacation, sickness, or police special events.

A Police Department posed the following question to Analysis & Inference: are similar answers on a promotion exam coincidences, or did they establish cheating by a defendant and another officer?

Statisticians may be most useful when there are no statistics. Yes, you read that correctly. One such example is a case of alleged age discrimination.
