Tóm tắt	A mobile semi-structured interview is a qualitative data collection technique in which a researcher conducts a guided yet flexible conversation with a participant using a smartphone or tablet — through voice calls, video calls, or messaging apps. It inherits the structured flexibility of the classic semi-structured interview while leveraging mobile technology to reach participants in naturalistic, convenient, or geographically dispersed settings.	Focus group research is a qualitative data-collection method in which a trained moderator guides structured discussions with homogeneous groups of six to ten participants to explore ideas, attitudes, and perceptions on a defined topic. Developed from sociological roots in the 1940s and systematised for applied research by Krueger and Casey, the method leverages group interaction as a data source — revealing not just what people think, but how they negotiate and articulate views in a social setting.
