Tóm tắt	Online non-participant observation is a qualitative data collection technique in which the researcher watches and records naturally occurring behaviour in digital settings — forums, social media platforms, chat groups, comment sections, or online communities — without joining, interacting with, or disclosing their presence to participants. The approach transplants the classical non-participant observation tradition into internet-mediated spaces, enabling study of authentic discourse and interaction as it unfolds organically.	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.
