    ABSTRACT: Psychological research involving scale construction has been hindered considerably by a widespread lack of understanding of coefficient alpha and reliability theory in general. A discussion of the assumptions and meaning of coefficient alpha is presented. This discussion is followed by a demonstration of the effects of test length and dimensionality on alpha by calculating the statistic for hypothetical tests with varying numbers of items, numbers of orthogonal dimensions, and average item intercorrelations. Recommendations for the proper use of coefficient alpha are offered. (PsycINFO Database Record (c) 2012 APA, all rights reserved)

    ABSTRACT: The book is a result of the author’s experience in building statistical models of real-world data. This problem is very general. It covers important topics of classical statistics, in particular exploring data, regression analysis, comparing means (t-tests), and factor analysis. Each problem is described with a thorough grounding in statistics through the use of SPSS for MS Windows. Numerous programs, all on the included CD-ROM, are used to give good examples. This very interesting book is written in an accessible style for students, researchers in the social sciences, psychologists, etc.
