To gain a comprehensive picture of the surveys that this methodology report references, see the Bureau of Sociological Research methodology reports for each survey available at this link. In the original survey reports the Bureau of Sociological Research staff provide descriptions of data collection, sampling and questionnaire design, response rate, data processing, and preliminary data cleaning. Introduction This report outlines the process of creating a raked weight variable for the NebrASKa Voices 2020 survey, a second “Wave 2” survey following four different “Wave 1” surveys. The 2020 NebrASKa Voices sample Wave 1 prior Nebraska Annual Social Indicators Surveys (NASIS) come from the NASIS conducted in Summer 2018 (N=116), Summer 2019 (N=162), Winter 2019 (N=55), and Winter 2020 (N=171). Participants in the four Wave 1 surveys were given the option to opt into future research; if they chose to opt in, they became part of the sampling frame for the Wave 2 NebrASKa Voices survey.
