What do mail surveys involve?-there is no direct interaction between the researcher and the respondent-respondants are sent a questionnaire in the mail, complete it and then they mail it back to the researcher, if he wants to get it back need to do certain things-a cover letter, explain who they are, purpose of the study and encourage people to complete it-a stamped self addressed envelope (makes it very convenient for respondent to complete)b)Some issues connected to mail surveysa.Sampling-probability sampling will be used-random selection with the sample, equal probability of being selected to the sample-sampling frame, some sort of list we can use to generate sample-needs to have names and addresses-if you don’t have names or sampling fram it can still be possible, you can use multi stagecluster sampling-you’ll then have addresses, all you can put is “occupant” when people receive a survey addressed to occupant, usually gets thrown out, result in a low response rateb.Response Ratei.What is the response rate?-is a percentage of people selected into a sample who actually participate in the surveyii.What is an adequate response rate?iii.How can the Response rate be increased?1.Monetary incentives (obviously with a sample of 2000-3000 cant make meaningful payments to that many people) has been found even relatively small monetary incentives do seem to have an impact on response rates-study in 1983 done by Paul Erdos, did research to try to test the effectiveness of monetary incentives, he mailed out a questionnaire to a sample of corporate executives, he divided them into 3 gfroups, some received no payment, some of these corporate executives received 10 cents, and some received 25 cents, what he found was 40% of those who ercieved no payment returened the questionaire. 10 cent group, 54% returned the questionnaire, the 25 cent group, 63% returned the questionaire2.Follow Up Mailing-an initial mailing, two or 3 follow up mailings afterwordsIe; original mailin (40%)- second another 20% (60%)- third 10%(70%)-three follow up mailings, increase response rate to about 75%iv.Asking Questions-lots of closes ended questions, some opened ended questions-people wont want to write out answers to long answer questions-difficult to get indepth informationv.Time and Monetary Investment-mail surveys require the second highest time and monetary investment, waitingfor the initial questionnaires to cme back
