How the poll was conducted: The Texas Hispanic exit poll was conducted by the Southwest Voter Research Institute (Now William C. Velasquez Institute) both on Election Day and during the early voting period throughout the state. In the Election Day exit poll, 1,511 Hispanic voters completed questionnaires in 39 polling places throughout the state of Texas in which at least 5% of the registered voters had Spanish surnames.
The Election day sample was designated by Dr. Karol Krotki, sampling statistician at the Institute for Survey Research, Temple University, to cover just over 91% of all Hispanic voters in Texas
The Election day design was a two-stage, probability-based sample. Precincts were first stratified by geography and size of Hispanic voter population and selected with probability proportional to the number of Hispanic registered voters. In the second stage, voters were selected systematically throughout the day until 6 p.m. within each of the precincts selected in the first stage.
All survey estimates generated from this poll have been weighted to reflect the actual distribution of Hispanic registered voters.
The poll was also conducted by the Institute among 389 Hispanic voters during the early voting period October 14-30 from a sample of counties comprising at least 5% Hispanic of registered voters and at least 5% Hispanic of registered voters and at least 100 Hispanic registered voters.
Finally, the two polls were merged and weighted to reflect the fact that early voters represented 32% and Election Day voters represented 68% of the total number of Hispanic voters.
The sampling error for most questions is plus or minus 2.5 percentage points with 95% confidence. That means that in 19 out of 20 cases, the results from the poll should differ by no more than 2.5 percentage points in either direction from what would have been obtained by interviewing all Hispanic voters in the state.
The poll was conducted with support from the Ford Foundation, the San Antonio Express-News, and KENS-TV, San Antonio's CBS affiliate.
