About this Poll
The Dallas Morning News-University of Texas Tyler poll is a statewide random sample of 1,169 registered voters taken over 10 days between Jan. 21-30. The mixed mode sample includes 305 registered voters who took the survey by phone and 864 registered voters who were randomly selected from a panel of registered voters that have opted in to take online surveys through a company called Dynata. The online and phone surveys were conducted in English and Spanish.

The data was weighted to be representative of the Texas registered-voter population. Iterative weighting was used to balance sample demographics to the state population parameters. The sample is balanced to match parameters for gender, age, race/ethnicity and education using an iterated process known as raking. These parameters were derived from 2018 Current Population Survey to reflect Texas’ electorate. The use of these weights in statistical analysis ensures that the characteristics of the sample closely reflect the characteristics of registered voters in Texas.

The poll’s sampling error for 1,169 registered voters in Texas is +/- 2.87 percentage points at a 95 percent confidence interval.
