All chapters except one are self-explanatory with nice formula sheet & no need for graphic calculator.
I understood the content, and it is relevant to my purpose of teaching students. I do not need to use graphic calculator or high fancy technology to do all the example problems, which is wonderful. The chapter on 2-way ANOVA test does not explain how to obtain the value of most of the variables needed to get the final test value (author only gave numbers but did not show calculations), and I figured out how to get the same numbers he did by fiddling with EXCEL and organizing the data into three groups (author did not organize the data) on EXCEL as well as looking up the internet on interaction formula since the author does not give it. Other than that chapter, the rest of the chapters were understood eventually by me but not very easy reading. I kept repeatedly reading till I understood the material, but it took several hours to understand the concepts for each chapter. A formula sheet is included, but it only goes to part of Ch. 13 and does not have all the formulas listed, so you should still review all the chapters to get all the formulas.
