Case study

An in-depth investigation of an individual, group or event, using detailed information.

An in-depth investigation of a particular person, group or event, often using several research methods.

Questionnaires, interviews, case studies and observational studies gather information without deliberately manipulating an IV. They can describe behaviour and experiences, but do not establish cause and effect on their own. No method is best for every question: choosing well means balancing control, realism, detail, practicality and ethics.

An in-depth investigation of an individual, group or particular case.

A case study is an in-depth investigation using several methods, not another name for an interview.

Do not claim that case studies only collect qualitative data: numerical test scores can supplement descriptions.

An in-depth investigation of one person, group or situation using detailed evidence.

This was a longitudinal single case study: one person was investigated in depth through repeated assessments over 21 years, from 1985 to 2006. It was not an experiment in which researchers deliberately caused or manipulated brain damage.

An in-depth investigation of one person or a small group, usually using several methods to gather detailed information.
