AO1 - Case Studies

• A case study is an in-depth study conducted into one group or one person (1). They can be over a long period of time and are often used alongside other techniques e.g. interviews, observations, questionnaires or a combination of all these, which produce in-depth qualitative data (1). Case studies may involve gathering data from the individual being studied but also from family and friends of the individual as well (1).
• Case studies can also use experiments and psychological testing producing quantitative data, alongside the qualitative data gathered.
