What will be an ideal response?
Without careful attention to sampling, measurement, and overall survey design, the effort is not likely to be effective; poor measurement—presenting clear and interesting questions in a well-organized questionnaire will help reduce measurement error by encouraging respondents to answer questions carefully and to take seriously the request to participate in the survey; nonresponse—the perceived benefits of survey participation have declined with decreasing levels of civic engagement and with longer work hours, perceived costs have increased with the widespread use of telemarketing and the ability of many people to screen out calls from unknown parties with answering machines and caller ID; inadequate coverage of the population—a poor sampling frame can invalidate the results of an otherwise well-designed study; sampling error—the process of random sampling can result in differences between the characteristics of the sample members and the population simply on the basis of chance.
