## Comprehending Behavioral StatisticsWhile this book provides the same material found in most introductory statistics texts, it goes beyond the standard by teaching students how to estimate statistics before computations are performed. The ESTAT software helps students build this skill by allowing them to learn to make accurate eyeball-estimates before ever touching a calculator. These estimation techniques are provided for both descriptive and inferential statistics. The ESTAT software is optional with the text, students can learn estimation from information in the book alone if you so choose. |
