Gr 4-8-These competent titles provide clear explanations of the topics under consideration. Both books include two-page chapters focusing on an element of the lead subject, beginning with simple aspects and building to the more complex. Data, for example, begins the discussion on graphs with a chapter on basic circle graphs. Subsequent chapters deal with more difficult concepts such as ogives and scatter plots. Each book includes step-by-step examples to illustrate each chapter. Gray sections at the bottom of every page provide definitions, helpful hints, and clarifying information. These books give students the opportunity to review and practice these concepts, but they may not be the best resources for introducing them.-Deanna Romriell, Salt Lake City Library, UT Copyright 2005 Reed Business Information.
