This is an introductory applied statistics text that can be used for a one - or two - semester course at either the undergraduate or graduate level. Central features are its hands-on approach; the use of real data; the wealth of exercises and illustrated examples using these data; the complete set of detailed answers to exercises in an appendix; the presentation of statistical methods with a clear, conceptual emphasis that includes an historical account of each method; and the integration of SPSS in a way that reflects statistical practice. Step-by-step instructions for using SPSS are provided as each new analytic procedure is introduced. A data CD is included with the text so that students may conduct their own statistical analyses and learn firsthand how statistics is used in practice. Conceptual understanding is emphasized through an exploration of underlying mathematical principles and real world applications. Uses the same real data sets repeatedly throughout the text to create a more cohesive presentation that links the different methods of analysis. Includes a data CD so that students may conduct their own statistical analyses.
