      • Participant: researcher becomes part of observation group
      • High EV- findings can be generalised
      • No demand characteristics- increases validity
      • Hard to replicate: less reliable
      • Ethical issues: makes people deliberately distressed

      • Comparisons can be made quickly
      • Easy analysis

      • Social desirability
      • Low objectivity

      • Unstructured: no set questions, more conversational
      • Semi structured: list of questions, has conversational feel
      • Easily replicated: results more reliable
      • Can acquire lots of  information
      • Difficult to analyse
      • Social desirability
      • Example: cognitive interview
    • Correlations
      • Researcher investigates an association between two variables: co-variables
