These two suveys are a panel study of the opinions of Texas voters before and after the July presidential debates by The University of Texas at Tyler in July. A unique aspect for this study was the ability to interview 770 registered voters again to see if their individual choices changed during the 4 days between the poll.
The poll was conducted over a four-day period (08/1/19 – 08/4/19). The first survey was alsoconducted over a four-day period (07/24/19 – 07/27/19).
The UT Tyler-Texas Opinion Survey poll was conducted using a Dynata panel of registered voters that opt-in to take surveys. This is known as Aristotle. The online panel generated a sample of 1261 registered Texas voters, 18 or older.
The data were weighted to be representative of Texas adults. The weighting balanced sample demographics to population parameters. The sample is balanced to match parameters for gender, age, race/ethnicity, and education using through an iterated process known as raking. These parameters were derived from 2016 Current Population Survey Voting and Registration Tables. The use of these weights in statistical analysis ensures that the characteristics of the sample closely reflect the characteristics of registered voters in Texas.
In this poll, the sampling error for 1261 registered voters in Texas is +/- 2.8 percentage points at a 95 percent confidence interval.
