The easy to use, hands-on "Personal Trainer CD-ROM" contains 43 short 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 keep up if they have to miss a class, and to review for exams. This CD-ROM 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 offers 15 graphical exercises, and includes datagen, the easiest-to-use statistical computational software. The "Personal Trainer CD-ROM" also includes interactive electronic review and multiple-choice quizzes. Students can click a "Transcript" button to produce word-for-word transcripts of each lectlet audio- a feature that is especially beneficial to ESL/ELL students. This CD-ROM is a dynamic and useful "after-class tutor" for any student struggling with statistics! All discussions of computational formulas (for standard deviation, variance, ANOVA, correlation, and regression) can be found in the "Resources" section of the "Personal Trainer CD-ROM," though the formulas remain in the text for reference.
