Written by six nationally recognized experts in the field, this new edition covers the major considerations, both classic and newly developed, in designing and conducting a sample survey. Topical, accessible, and to-the-point, this update represents the state-of-the-science in survey methodology with a new focus on the increasing use of the internet for conducting survey research and the growing presence of mobile phones rather than landlines in residential homes.
