he University of New Orleans’ Survey Research Center (SRC) conducted a statewide interactive voice response (IVR) survey of Louisiana voters on the topic of who they preferred in the 2020 presidential election. We also asked them about the Covid-19 virus. Survey respondents were randomly selected from the Louisiana Secretary of State’s voter file. However, not all registered voters were eligible for the poll. Only those registered voters who had voted at least once in the past ten statewide elections in Louisiana were selected for the sample. The sample of 755respondents was collected by telephone IVR on Thursday October 22, 2020 and yields a margin of error of +/- 3.6% with 95% confidence.
Readers should be cautious in making narrow inferences about sub-categorical cross tabulations of survey results. While a poll of 755 random respondents yields a +/- 3.6% margin of error, sub-categorical group samples by race, age, and gender are smaller than the total sample size, thus, leading to wider margins of error when they are reported in cross tabulations.
