This document discusses different types of audience research methods and purposes. It describes quantitative research as statistics-based, while qualitative research focuses on reasoning and social/cultural factors. Primary research involves collecting first-hand data through methods like questionnaires with open or closed questions. Secondary research uses already existing data from reports and publications. Research can be done for demographic purposes like age and gender, geodemographic to target specific geographical areas, or psychographic to study attitudes and lifestyles. Audience profiling considers socioeconomic status, region, age, gender, sexual orientation, race, as well as whether the audience is mainstream or niche.
