Data for Meer Research is collected using automated polling (IVR or interactive voice response), online panels, and/or call centers utilizing computer-assisted telephone interviewing (CATI). A survey may use a single mode of data collection or a combination of methods depending upon the sample desired. If a combination of IVR and CATI for cell phone calling is used, the samples will be mutually exclusive.
The sampling method for each survey will be fully disclosed upon publication. Regardless of the technology used for data collection, the survey instrument (script) remains the same.
Calls are placed to randomly-selected phone numbers through a process that insures appropriate geographic representation. Calls are placed from 5 pm to 9:30 pm local time on weekdays, and Saturday and Sunday calls are made from 1 pm to 6 pm local time.
Once data is collected, the raw data is weighted according to known demographic factors such as age, race, gender, and political party to adjust for sampling deviations from population values.
For political surveys, data is augmented by voter-file data and a series of screening questions to determine likely voters.
