The 2007 Texas Lyceum Poll is a random-digit dial telephone survery of Texas
adults. Telephone coverage within the state of Texas is approximately 97%. Randomized
selection procedures were assiduously followed throughout the process, even at the level
of selecting individuals within the household. The final sample size is 1,000 adult
Texans. The instrument itself relies on questions that have been used previously in
national polls, and have been shown to be both valid (correlating with plausible
independent and dependent variables) and reliable (robust to question order and
interviewer effects). A Spanish version of the instrument was developed and respondents
were given a choice of participating in English or Spanish. Bilingual interviewers were
utilized, and approximately 60 interviews (6% of the sample) were completed in Spanish.
The overall response rate (completed interviews / contacts) is 40%. This rate is partially
the result of an extended time in the field, which facilitated call-backs. The overall
margin of error for the sample is +/- 3.0 percentage points at the 95% confidence level.
The data used to generate top-lines and tables are weighted by U.S. Census Bureau
estimates with respect to age, gender, and race. For example, Census data indicate
the proportion of 18-29 year old Hispanic females in Texas, and we use these estimates to
weight the survey data. As expected, the most significant weights are applied to young,
male, minority respondents (who are under-represented here, as they are in almost all
polls in the U.S.).
