This update of the successful self-teaching guide introduces the basic concepts and procedures of statistics in all its popular applications. Purely a `how-to' book, it integrates actual interpretations of computer statistical programs that show readers how to perform a number of useful statistical tests and procedures and select the most appropriate ones in given circumstances. Topics include basic skills, populations and samples, estimating, hypothesis testing, difference between means, the difference between two variances on several means, the relations between two sets of measures, a test of distributions, and the combined effects of two variables. Features numerous tables, including reference formulas, squares and square roots, and binomial probabilities.
