Hurlburt's text offers an innovative approach to teaching and understanding statistics. Many students consider statistics their most intimidating subject, but Hurlburt uses a variety of learner-friendly approaches to help students to think clearly and confidently about statistical concepts. Students find his writing style inviting and clear; faculty find it exceptionally accurate and up to date. He provides a complete set of interactive audio/visual lectures (called "lectlets") to engage students who find that hearing enhances their comprehension. Hurlburt deftly employs repetition and a progressive, cumulative integration of concepts, so students build upon what they learn as they progress through the course. Hurlburt's unique "eyeball-estimation techniques," which garnered high praise in previous editions, helps students gain experience in making educated guesses! New to this edition, COMPREHENDING BEHAVIORAL STATISTICS, THIRD EDTION, includes a FREE Personal Trainer CD--This hands-on CD contains 43 interactive audio/visual lectures (called "lectlets") covering all the concepts in the text. Students use the lectlets to prepare for class, to clarify concepts they didn't understand in class, to substitute for a missed class, and to review for exams. The FREE Personal Trainer also includes ESTAT, Hurlburt's unique eyeball-estimation software, which enables students to make an educated guess about the magnitude of a statistic without the use of a calculator or statistical tables. ESTAT includes datagen, the easiest-to-use statistical computational software. The Personal Trainer CD also includes interactive electronic review and multiple choice quizzes. The Personal Trainer CD is a dynamic and useful "after-class tutor" for any student struggling with statistics.
