Books by Jacob Cohen

This non-technical guide to power analysis in research planning in the behavioural sciences, provides users of applied statistics with the tools needed for more effective analysis. This edition includes a new chapter covering power analysis in set correlations and multivariate methods.

This third edition continues in the tradition of the broadly-used system first developed by the authors but with many modifications to reflect modern and developing practices in the field. It includes an increased emphasis on graphical presentations used throughout the text.
