The illustrative examples used throughout the text have obviously been selected with the intention of providing the greatest possible insight into the procedures and, although a few typographical mistakes were noted, no serious errors of any kind were found. It is unfortunate, though, that a diagram on p. 150 showing Theil regression fitted to a set of data previously fitted by least squares accidentally fails to show the rogue point which is central to the discussion. A strength of the book is that it repeatedly stresses the assumptions which must be satisfied if an application of a particular procedure is to be valid. It provides simple explanations of the rationale behind these procedures, but mostly omits any detailed theoretical treatment, indicating instead where this can be found if needed. An ample bibliography is provided. One surprising omission, perhaps, in a book designed to give a broad introduction to non­ parametric techniques is that of runs tests, which include the best known and easiest to apply tests for randomness in a sequence of observations. But with this one exception, the coverage is good. The book is intended as an introductory text for undergraduates in statistics and as a practical guide to research workers in other disciplines. It fulfils this role excellently and, in addition to providing a good exposition of the standard procedures, Professor Sprent has con­ tributed much useful insight of his own.
