This introductory statistics textbook is "compassionate" in that it addresses the statistical tools important to the social service professions and in that it minimizes theory in preference of social service examples that demonstrate the use of quantitative analysis and eliminates mathematical equations and formulas. Faherty (U. of Southern Maine) discusses levels of data; presenting data tables and figures; mean, median, and mode; standard deviations, ranges, and quartiles; other descriptive statistics; probability and statistical significance; chi-square test of independence; scattergrams and correlation; Spearman's rho, Pearson's r, and correlation; t-test for paired and independent samples; one-way analysis of variance with post hoc tests; and nonparametric alternatives to common parametric tests. The volume is intended to serve either as a conceptual introduction or as a companion to more rigorous and traditional texts. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
