Bøger af Donald T. Campbell

Suitable for researchers, evaluators, and graduate students, this title includes the author's arguments as to why qualitative approaches belong with quantitative ones as the assumptive background to relevant quantitative measures, his debate with deconstructionists and social constructionists on measurement validity, and more.

Regression toward the mean is a complex statistical principle that plays a crucial role in any research involving the measurement of change. This primer is designed to help researchers more fully understand this phenomenon and avoid common errors in interpretation.

This updated edition of Unobtrusive Measures builds on the earlier version's drive to justify novel techniques of survey and archival research. This book encourages and motivates ingenuity in obtaining information. The authors combine different methods so that research results can withstand the 'threats to validity'.

This book provides researchers, evaluators, and graduate students with a user-friendly presentation of Campbell's essential work (including his thoughts on some of his classic works) in social experimentation.
