Aim of the course

This course on nonresponse processes, bias and weights enables participants to prevent nonresponse, analyse nonresponse biases and calculate adjustment weights. In addition, the instructor supports participants with nonresponse problems in their own research.


  • Preventing nonresponse: survey design aspects
  • Mixed-mode surveys
  • Sampling, non-coverage en nonresponse
  • Data-collection processes
  • Nonresponse rates and nonresponse bias
  • Interviewer effects
  • Using paradata to identify nonresponse bias
  • Nonresponse weight: propensity score weights and calibration

Target audience

Experienced researchers developing or commissioning surveys; Researchers using secondary data and looking for strategies of dealing with nonresponse
