Purpose and Concepts<span class=\"ez-toc-section-end\"><\/span><\/h4>\r\n<p>The first webinar video in the series introduces concepts that lead to understanding survey research and unit nonresponse.<\/p>\r\n<h4><span class=\"ez-toc-section\" id=\"Part_2_%E2%80%93_Impact_of_Ignoring_Nonresponse\"><\/span>Part 2 &#8211; Impact of Ignoring Nonresponse<span class=\"ez-toc-section-end\"><\/span><\/h4>\r\n<p>The second webinar video in the series demonstrates the impact of ignoring unit nonresponse in survey research and using complete-case analysis on claims and conclusions made from survey or questionnaire data. The methods and statistics research literature often describe data analysis that ignores nonresponse as <em>naive,<\/em> but perhaps a more fitting descriptor is when an analyst or researcher is <em>blissfully unaware<\/em>.<\/p>\r\n<h4><span class=\"ez-toc-section\" id=\"Part_3_%E2%80%93_Tools_to_Adjust_for_Nonresponse\"><\/span>Part 3 &#8211; Tools to Adjust for Nonresponse<span class=\"ez-toc-section-end\"><\/span><\/h4>\r\n<p>The third webinar video in the series aims to present a sample of the tools often used to adjust for unit nonresponse, including when these tools can be applied. 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.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Citation\"><\/span><strong>Citation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>Woitschach, P., &amp; Zumbo, B.D.
