Gamma
A measure of association; a statistic used with ordinal variables.

Generalizability
The extent to which the findings of a study can be applied to other populations, settings, or times. FOR EXAMPLE, the findings that a treatment program for adult females reduced recidivism may not be subsequently generalized to include adult males or juveniles.
