Document Summary

Length: depends on topics, respondents, and methods of administration. Question order or sequence: organization of questionnaire, order effects. E. g. (cid:862)if (cid:455)es, go to this (cid:395)uestio(cid:374)(cid:863) (cid:862)if (cid:374)o, go to this (cid:395)uestio(cid:374)(cid:863) Arranged in way to avoid bias; keep people on their toes. Can see if people were actually paying attention/if answers clash. Order effects occur when responses to earlier items influence responses to later items. Another example of priming: free speech opinion poll. Both sets of items have the same second item. Response rate number of people participating in a survey divided by the number selected in the sample, in the form of a percentage; also called completion rate or in self-administered surveys, the return rate (page 221) Probe technique employed in interviewing to solicit more complete answer to a question; nondirective phase or question used to encourage response (page 226) E. g. (cid:862)a(cid:374)(cid:455)thi(cid:374)g (cid:373)o(cid:396)e? (cid:863) o(cid:396) (cid:862)ho(cid:449) so? (cid:863)
