AmeriSpeak Calibration is an option for researchers seeking the accuracy of the probability-based AmeriSpeak Panel and the scale and reach of non-probability samples.
Examples include studies of local areas, tracking surveys requiring large sample sizes of the general population, or studies of rare subpopulations.
In a blended-sample solution, AmeriSpeak Calibration combines AmeriSpeak and non-probability sample interviews, with AmeriSpeak providing the calibration weights to address self-selection, non-response, and non-coverage biases in the non-probability samples.
For studies requiring a 100% probability sample, additional probability-based sample can be recruited for a specific project or as part of a custom panel solution. Visit our Custom Propriety Panels page for more information.
