Pew Research Center · Princeton Survey Research Associates International (PSRAI)
A 32-question quiz on the Bible, world religions, and church-state law, fielded May 19–June 6, 2010 among 3,412 U.S. adults by landline and cell phone. The survey oversampled Jewish, Mormon, and atheist/agnostic respondents by recontacting people previous surveys had identified as belonging to those groups, which makes it one of the few Pew datasets from this era with a usable standalone Mormon subsample on a knowledge (rather than belief/practice) battery.
