The Fifth Edition of Floyd J. Fowler Jr.'s bestselling Survey Research Methods presents the very latest methodological knowledge on surveys. Offering a sound basis for evaluating how each aspect of a survey can affect its precision, accuracy, and credibility, the book guides readers through each step of the survey research process. This fully updated edition addresses the growth of the Internet for data collection and the subsequent rapid expansion of online survey usage, the precipitous drop in response rates for telephone surveys, the continued improvement in techniques for pre-survey evaluation of questions, and the growing role of individual cell phones in addition to--and often instead of--household landlines. Throughout the book, the author puts the profound changes taking place in the survey research world today into perspective, helping researchers learn how to best use new and traditional options for collecting data.
