Modular chapters provide a more in-depth exploration of these topics, as well as Experimental Design. Weiss takes a step by step approach to statistics covering topics, procedures, and techniques thoroughly and precisely. No assumptions are made as to students abilities, which ensures that they cover all need material. In most examples and exercises, the author has presented raw data in addition to summary statistics. This gives a more realistic view of statistics and provides an opportunity for the problems to be solved by computer if desired.
