Contrast Analysis: Focused Comparisons in the Analysis of Variance.

Cambridge: Cambridge University Press (CUP), 1985. Paperback trade, very good plus condition, minor edgewear, rubber stamp. 107 pp. Robert Rosenthal and Ralph Rosnow explain how contrast analysis permits us to ask more focused questions of our data. In return for a small amount of simple computation, we get greater statistical power, and can make clearer substantive interpretations of the research results. Contrast analysis is employed within analysis of variance (ANOVA) whenever the numerator degrees of freedom are greater than one (which is most of the time). Unfortunately, it is employed rarely by behavioural and social scientists. This book is a non-mathematical account enabling researchers to address focused questions posed by theories, hypotheses, and hunches. Many researchers in the behavioural and social sciences, education and business should find this book useful.
