How Big Should My Sample Be?: A Guide for Health Researchers

This really useful reference book is for students and triallists and is the ideal guide for peer reviewers who are not trained in sample size calculation.
It is for people organising a research project who want to know how many people they will likely need. It also contains an introduction to statistical ideas for people who have not studied the subject.
It uses the method of programmed instruction making it suitable for people without a teacher to learn by themselves.
