Though briefer than Statistical Methods for Educational and Psychology, Third Edition, the approach of Basic Statistics for the Behavioral Sciences, Third Edition is the same: conceptual rather than mathematical. The authors stress the understanding, applications, and interpretation of concepts rather than derivation and proof or hand-computation. Selection of topics in the book was guided by three considerations: (1) What are the most useful statistical methods?; (2) Which statistical methods are the most widely used in journals in the behavioral and social sciences?; and (3) Which statistical methods are fundamental to further study?
