The American Association for Public Opinion Research (AAPOR) is an organization made up of people who study things like what most people think about different topics. They want to know things like, "Do most people like pizza?" or "Do most people think anime is cool?" Through their research, AAPOR members look at how people think and feel about different things, which can help marketers, politicians, and businesses make decisions. AAPOR members also work together to make sure their research is done accurately and carefully.
