However, semi-structured interviews allow the interviewer to diverge into other topics when it feels appropriate to do so while also covering questions which are mandatory to bring up in the interview …show more content…

The best sampling method for semi-structured interviews would be purposive sampling, since the interview may involve particular topics which the participants must know in order for the experiment to have rich data. As mentioned before, interviewers conducting semi-structured interviews must undergo training in order for them to not suggest answers that the participant may infer. Training is also required for the interviewer to stray into other topics while still managing to follow the necessary topics. After the interview, it is vital that the researcher debriefs the participant. The process allows the participants to ask questions about the experiment as well as the researcher to clearly explain what the experiment was about (Gliston, 2015). The debriefing of the experiment may be weaved into the semi-structured interview if at the end of the interview, the experiment also ended for the
