  • interviews
    • unstructured
      • The interaction between the participant and the interviewer allows for richer, more valid data. This is because the interviewer can ask follow up questions
      • Also the interaction allow the interviewer to develop a relationship with the participant which could mean they are more open and honest with their answers
      • Ambiguities in an answer can be probed to further understand the meaning of that answer
      • The interviewer can change the questions if, over the course of the study they think the hypothesis should change or they want to take the study in a new direction
      • weaknesses
        • trained interviewer who can only interview one participant at a time, this means this method is time-consuming and costly
        • interviewer won’t ask exactly the same question every time, so it could be said that this method is less reliable
        • changing questions also mean it is difficult to replicate the study.
        • data is qualitative which means it is hard to analyse and compare with other pieces of data
    • structured
      • Interviewer can explain the questions and overcome illiteracy problems
      • Data can be seen as reliable as all the participants are answering the same questions
      • These interviews use pre-coded questions, which make the data easier to compute and analyse than the data gained in unstructured interviews
      • The interviewer has little interaction with the participant so there is less chance of interviewer bias than in unstructured interviews.
      • weaknesses
        • The structure of the interview means the interviewer can’t probe and ask further questions, so the data isn’t as rich
        • They are more time consuming and expensive than other methods
        • There is still the risk of interviewer bias
    • semi-structured
      • positive rapport between interviewer and interviewee
      • high validity, can talk in detail and depth
      • can clarify any confusing questions
      • weaknesses
        • depends on the skill of the interviewer
        • can give out unconscious signals
        • time consuming and expensive
        • not very reliable
        • difficult to generalise
        • validity, don't know if lying
    • group
      • Focus groups
      • weakness
        • easy for a focus group facilitator to guide the group down a particular line of thought
        • group members to be swayed by a few dominant characters in the group.
      • generalsable
      • develop and expand ideas
      • more comfortable and open
