Experimental and Quasi-Experimental Designs... - Campbell and Stanley

Description

Experimental and Quasi-Experimental Research Designs by the well-known authors Donald T. Campbell and Julian C. Stanley. This book demonstrates the great potential of statistical techniques and warns beginners in behavioral science research against certain fallacies and naiveties. It discusses alternatives in designing experiments, with particular attention to problems of controlling extraneous variables and threats to validity. Readers learn to distinguish between internal validity and external validity, and for the purpose of interpreting results, a checklist of validity factors is provided.
