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 surveys a. 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 stage cluster 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 rate b. Response Rate i. What is the response rate? -is a percentage of people selected into a sample who actually participate in the survey ii.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 questionaire 2. Follow Up Mailing -an initial mailing, two or 3 follow up mailings afterwords Ie; 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 information v. Time and Monetary Investment -mail surveys require the second highest time and monetary investment, waiting for the initial questionnaires to cme back
-waiting for the follow up questionnaires to come back -the cost of mailing the questionnaires, the prepaid letters back as well Interview Surveys a) What do interview surveys involve -direct interaction between researcher and respondent -interviewer reads questionnaire, records the respondents answers b) Some Issues connected to Interview surveys a.
