This document discusses focus groups, including their history, purpose, advantages, disadvantages, best practices, and costs. Focus groups originated in the 1940s to evaluate audience responses and were later adopted by businesses. They involve organized interviews of small groups to discuss select issues and yield useful information for program design and evaluation. Key advantages include obtaining diverse perspectives and ideas in a time-efficient manner. Potential limitations are non-representative findings and one group dominating. Moderators must ensure discussions remain balanced and confidential. Planning, participant selection, facilitation, and data analysis are important for high-quality focus group research.
