A semi-structured interview is a qualitative research method undertaken to answer set questions while also giving the interviewer the opportunity to explore other areas of discussion (Evaluation Toolbox, 2010). Unlike questionnaires, interviews involve social interaction and require participants to essentially give data straight to the researcher of the experiment (McLeod, 2015). Structured interviews are generally formal and make the interviewer follow a strict set of questions so they do not stray into other questions that are not necessary. 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…
Three sampling methods involved in qualitative research include purposive sampling (researcher gathers participants based on what they know), snowball sampling (researcher gathers participants, participants contact other individuals to participate) and convenience sampling (researcher gathers participants who are available at the time). 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
