Following an introduction to basic statistics, the book provides chapters on measurement, data organization, percentiles, measures of central tendency, measures of dispersion, and the normal curve. Probability theory and statistical inference using one sample, two samples, and multiple samples are presented. Further chapters discuss correlation, regression, multivariate analysis, and nonparametric studies. Each chapter ends with a list of main terms and symbols and a set of exercises to which answers are provided at the book's end. Figures, tables, footnotes, an index, a bibliography of about 130 entries, and appendixes presenting a glossary of symbols, a list of formulas, and standard statistical tables, are included.
