A Quasi-Sampling Theory of the Generalization of Causal Relationships.

Cook, Thomas D.

New Directions for Program Evaluation, n57 p39-82 Spr 1993

A practical theory is offered for probing external validity, the generalization of causal relationships. This alternative theory is built around five principles abstracted from research on construct validation. It emphasizes purposive sampling for theoretical ends rather than random sampling to represent a population. (SLD)
