Presents a unified method for conducting good survey research centered on the various types of errors that can occur in surveys - from measurement and nonresponse error to coverage and sampling error. This comprehensive guide is built on theoretical elements drawn from specific disciplines, with detailed treatments of the specific types of errors.

Using an expository style that builds from simpler to more complex topics, this text explains how to measure the centre and variation on a single variable. It also considers ways to examine the distribution of variables and measure the spread of a variable.

This book describes how surveys are conducted in such a way that they can be believed, explains how to read statistical reports and analyze data and provides guidelines that are useful in evaluating polls.
