Statistics at Square Two, Second Edition, by Michael J. Campbell, is an updated version of the sequel (published in 2001) to the popular Statistics at Square One, published more than 30 years ago. At just over 140 pages, this text contains a lot of useful information. Intended as a quick reference of statistical methods prevalent in medical literature, Statistics at Square Two does not contain much theory; instead, Campbell focuses on the practical application of these methods. The text explains the benefits and pitfalls of these various methodologies and includes complete references, exercises, and frequently asked questions at the end of each chapter. Campbell uses Stata 8 throughout this text.

Like its predecessor, this text covers classical analyses such as means and medians, t tests, and chi-squared tests. The text also covers the more complex methods that have become available to medical researchers through advances in computer technology. The newer methods the text covers include multiple regression, logistic regression, survival analysis including Cox regression, random-effects models, and Poisson and ordinal regression. 公卫考场
