An introduction to the use of statistical tests in psychology experiments for undergraduate level students, designed to enable students to select appropriate statistical tests to evaluate the significance of data obtained from experiments. The main change from the previous edition (first published in 1982, with frequent subsequent reprints) is a new format which divides the text into three parts addressing a general introduction, basic non-parametric tests, and multivariable designs. The new edition also introduces students to the use of computerized statistics packages. Distributed by Taylor & Francis. Annotation c. Book News, Inc., Portland, OR (booknews.com)
