Case studies

• Case studies strengths

  Used to investigate human behaviour that can’t be replicated in a lab setting.

  Get in depth rich quantitive data because of close interaction many factors can be studied where as experiments all variables need to be controlled
• Case study weaknesses

  > Its difficult to generalise from individual cases

  > Can’t make before and after comparisons

  > Issues with confidentiality as some cases are easily identifiable because of their unique case

  > evidence may be unrealiable as information is collected from past events
