Kurzbeschreibung
Now in its third edition, this accessible text continues a thorough discussion of basic statistical methods, presentations, approaches, and modeling techniques. With new examples and counterexamples from the latest research as well as added coverage of relevant topics (data quality assessment, correlated data, data analysis, report preparation, factor analysis), this new edition addresses popular mistakes in data collection and provides an indispensable guide to accurate statistical analysis and reporting. The authors' emphasis on careful practice, combined with a focus on the development of solutions, reveals the true value of statistics when applied correctly in research.
