Sintesi	A face-to-face focus group is a structured, moderated group discussion conducted in a shared physical space, typically with 6–10 participants who are selected because they share a relevant characteristic. The moderator follows a semi-structured topic guide to elicit opinions, perceptions, and experiences. Unlike surveys, focus groups capture social interaction — agreement, disagreement, and the group dynamics through which attitudes are formed and expressed.	An online focus group is a moderated group discussion conducted via internet-based platforms — video conferencing, text chat, or asynchronous forums — to explore shared perceptions, attitudes, and experiences on a defined topic. It inherits the group-interaction dynamics of the traditional focus group while removing geographic barriers and enabling data collection from dispersed or hard-to-reach populations.
