This three-part expository webinar was created by Dr. Pamela Woitschach and Professor Bruno Zumbo. This project was part of Dr. Woitschach’s part-time fellowship with the BC Support Unit Patient-Centred Measurement methods cluster and BC Office of Patient-Centred Measurement (BCPCM) with matching funds from the UBC-Paragon Research Initiative. She is a UBC-Paragon Postdoctoral Research Fellow in the UBC Measurement, Evaluation, & Research Methodology Program under Professor Bruno Zumbo’s supervision. The project ran from October 15, 2019, to March 31, 2021.

The Unit Nonresponse webinar is organized in three parts that will allow our audience to be engaged with the information they consider relevant to their interests.
It is important to keep in mind that the webinar was created for data analysts and applied researchers who work with data to respond to research questions but who are not steeped in the research literature in statistical science and mathematical statistics.

The three parts to the webinar series:
Part 1: The first webinar video in the series is focused on introducing the concepts leading to an understanding of survey research and unit nonresponse.

Part 2: The second webinar video in the series demonstrates the impact of ignoring unit nonresponse in survey research and using complete-case analysis.

Part 3: The third webinar video in the series aims to present a sample of the tools often used to adjust for unit nonresponse. Part 3 also includes two short videos, syntax and code demonstrating how to use a propensity score weighting approach using SPSS and separately using R with an example data file in various formats.

Topic – Notes in PDF , and, where appropriate, data files and R code or SPSS files
