Case studies

• A case study is an in depth study which gathers lots of detail on one person or group
• One limitation of case studies is that they cannot be generalised easily because they have a small sample size
• Another limitation of case studies is that it can be difficult to control variables as the researcher has little influence over what happens
• Case studies also have high ecological validity as they take place in real life situations
• Case studies are useful when studying rare behaviours or disorders .
• Case studies gather qualitative data, which is detailed but is interpreted subjectively
