Introduction to Statistics, 9E provides a first exposure to elementary statistics for liberal arts students nationwide. The textbook includes a focus on technological skills to increase statistical literacy, with detailed explanations presented in an easy conversational writing style. The text uses a step-by-step problem-solving approach that helps students understand complex statistical concepts, while incorporating educational trends that stress student understanding of basic statistical concepts with the help of technological devices.

Suitable for use in a one- or two-semester course, the text contains fourteen chapters of descriptive statistics, probability, probability distributions, various models of hypothesis testing, and linear regression. Interpretation of calculator and statistical software output is integrated throughout the text, and numerous problem sets offer questions that both test basic statistical concepts and challenge students’ critical thinking skills.
