Elon University Poll Methodology The Elon University Poll uses random computer generated telephone numbers from across the state of North Carolina. Random generation of telephone numbers allows for dialing both listed and unlisted numbers. The sample of possible numbers is weighted proportionally to reflect the distribution of phone numbers in each telephone exchange in the state, as well as each county. During each poll, phone numbers are released by computer to phone interviewers in groups of 100 numbers. This enhances the reliability of surveys by controlling how many numbers are available to the interviewers at any one time. Three attempts to complete an interview are made for each number released to an interviewer, with second and third attempts to reach respondents staggered throughout the survey. Non-residents of households are not surveyed and no interviews are taken from businesses. Survey data only reflect interviews with North Carolina residents age 18 and older. Polls are normally conducted from 5:30 - 9 p.m., Monday through Thursday. Each poll typically has a margin of error of ± 4.5 percent, and samples approximately 600 citizens.
