Drawing upon over 40 years of teaching experience, the authors of this highly accessible book provide a clear and methodical approach to essential statistical procedures. They use plain language to explain concepts, employ engaging examples, and incorporate extensive exercises to insure a better understanding of the material. The book successfully demystifies such commonly troublesome topics as the standard deviation, hypothesis testing, confidence intervals, degrees of freedom, p-values, and estimates of effect size. Throughout its pages, concepts are emphasized rather than computations.
