In a short essay, list and discuss the three primary methods researchers use in an attempt to improve response rates

What will be an ideal response?

a. Prior notification - this consists of sending a letter or e-mail, or making a telephone call to potential respondents, notifying them of the imminent mail, telephone, personal, or electronic survey. Prior notification increases response rates for samples of the general public because it reduces surprise and uncertainty and creates a more cooperative atmosphere.
b. Incentives - offering monetary as well as nonmonetary incentives to potential respondents can increase response rates. Monetary incentives can be prepaid or promised. The prepaid incentive is included with the survey or questionnaire. The promised incentive is sent to only those respondents who complete the survey.
c. Follow-up - contacting the nonrespondents periodically after the initial contact, is particularly effective in decreasing refusals in mail surveys. The researcher might send a postcard or letter to remind nonrespondents to complete and return the questionnaire. Follow-up can also be done by telephone, e-mail, or personal contact.
