Summary of Course:
In light of declining nonresponse rates in sample surveys, the attention of survey methodologists is turning from nonresponse rates towards the relationship between nonresponse rates and nonresponse bias. This course is designed to help conducting nonresponse bias studies when response rates are less than 80 percent or there is reason to suspect that estimates are biased from nonresponse. Practical tools are described and examples are used to illustrate methods that can be used to conduct these studies. The advantages and disadvantages of these methods are presented, and the value of having multiple approaches is highlighted. The need to devise strategies for nonresponse and for its analysis in the planning stage, prior to completing the survey are emphasized. The course focuses primarily on unit-nonresponse.
- To provide participants with an understanding of the consequences of nonresponse for survey data analysis and survey quality
- To provide participants with practical tools to examine nonresponse bias in surveys
This course will include the following topics:
- Factors which affect non-response
- Methods to analyse nonresponse bias in surveys
- Methods for reducing non-response
- Modelling approaches to non-response
The course will have a strong practical emphasis, including workshop sessions to enable participants to work through examples.
The course is aimed at both at researchers who design surveys and wish to reduce non-response and at researchers who analyse survey data and wish to compensate for the effects of non-response. The course is especially for those in the social, economic, educational and medical sciences and those working in government and official statistics and survey agencies.The course is suitable for statisticians or for social scientists who have a basic familiarity with statistical ideas of estimation in surveys.
Examples will be presented and only rudimentary statistical knowledge of concepts such as bias and variance of the estimates is required of participants.The course will have a practical emphasis, with regular workshop sessions using real survey data, to enable participants to work through examples.
Although no formal pre-requisites are necessary participants may find it useful to also attend the course ‘Handling Nonresponse in Sample Surveys’, 10-11 March 2008, which will provide a good introduction to the topic.
Participants will receive written course notes.
Robert. M. Groves is Research Professor at the Joint Program in Survey Methodology and Director, University of Michigan Survey Research Center. He is the author of Survey Errors and Survey Costs and co-author of the new text Survey Methodology (both by Wiley). He is a student of survey participation, working now on behavioral foundations of decisions to participate in surveys and the determinants of nonresponse error arising from nonparticipation. He has extensive experience in the delivery of short courses, particularly on nonresponse.
