Unformatted text preview: 13 1.7 Exercises For Further Reading The American Statistical Association series “What is a Survey?” crevides an intro— duction to survey sampling, with examples of many of the concepts discussed in Chapter 1. In particular, see the chapter “Judging the Quality of a Survey.” This series is available on the American Statistical Association Survey Research Methods Sec— tion website at wwwarnstat.org/sectionslsrrnsl. The American Association of Public Opinion Research website, wwwaapororg, coatains many resources for the sampling practitioner, including a guide to Standards and Best Practices. The following three books are recommended for further reading about general issues for taking surveys. Groves et al. (2009) discuss statistical and nonstatistical issues in survey sampling, with examoles from large—scale surveys. Biemer and Lyberg (2003) provide a thorough treatment of issues in survey quality. Dillrnan et ai. (2009) give practical, research-supported guidance on everything from questionnaire design to choice of survey mode to timing of follow-up ietters. If you are interested in more information on questionnaire design and or on pro- cedures for takin g social surveys, start with the books by Presser et a1. (2004), Fowler (1995), Converse and Presser (1986), Schuman and Presser (1981), and Sudman and Bradburn (1982). Much recent research has been done in the area of using results from cognitive psychoiogy when writing questionnaires: Tanur (i992), Sudrnan et a]. (£995), Schwarz and Sudinan (1996), Tourangeau et al. (2000), and Bradburn (2004) are useful references on the topic. All are clearly written and list other references. In addition, many issues of the journal Public Opinion Quarterly have articles dealing with questionnaire design. xv ll Exercises A.

BMWQE 1 The article “What Readers Say about Marijuana” (Parade, July 31, 1994, p. 16) reported “More than 75% of the readers who took part in an informal PARADE f telephone poll say marijuana should be as legal as alcoholic beverages.” The telephone y. poll was announced on page 5 of the June 12 issue; readers were instructed to “Call 1 is l~900—773»1200, at 75 cents a call, if you would like to answer the following questions. I Use touch-tone phones only. To participate, call between 8 am.

In the fourth quarter of 1994, 100,300 g‘ury summons were mailed to Maricopa County, Arizona, residents. Approximately 23,000 of those were returned from the post office as undeliverable. Approximately 7000 persons were unqualified for service because they were not citizens, were under 18, were convicted felons, or other reason that disqualified them from serving on a jury. An additional 22,000 were excused from jury service because of illness, financial hardship, military service, or other acceptable reason. The final sample consists of persons who appear for jury duty; some unexcused jurors fail to appear. Many scholars and policy makers are interested in the proportion of homeless people who are mentally ill. Wright (£988) estimates that 33% of all homeless people are mentally ill, by sampling homeless persons who received medical attention from one of the clinics in the Health Care for the Homeless (HCH) project. He argues that selection bias is not a serious problem because the clinics were easily accessible to the homeless and because the demographic profiles of HCH clients were close to those of the general homeless population in each city in the sample. Do you agree? Approximately £6,500 women returned the Healthy Women Survey that appeared in the September 1992 issue of Prevention. The May 1993 issue, reporting on the survey, stated that “Ninety—two percent of our readers rated their health as excellent, very good or good.” A survey is conducted to find the average weight of cows in a region. A list of all farms is available for the region, and 50 farms are selected at random. Then the weight of each cow at the 50 Selected farms is recorded.

(1993) mailed surveys to all 184 licensed homes in Washington State, directed to the administrator and food service manager. Of those, 43 were returned by the deadline and included menus. Entries in the online encyclopedia Mkipedia can be written or edited by anyone with Internet acoess. This has given rise to concern about the accuracy of the information. Giles {2005) reports on 3 Nature study assessing the accuracy of Wikipedia science articles. Fifty subjects were chosen “on a broad range of scientific disciplines.” For each subject, the entries from Wikipedia and Eucyclopaedia Britram'ca were sent to a relevant expert; 42 sets of usable reviews were returned. The editors of Nature then tallied the number of errors reported for each encyclopedia. The December 2003 issue of PC World reported the results from a survey of over 32,000 subscribers asking about reliability and service for personal computers and other electronic equipment. The magazine “invited subscribers to take the Web-based survey from April 1 through June 30, 2003” and received 32,051 responses.
