What is a Case-Control Study?

Case-control studies are a type of quantitative research "designed to sample a group of people with and a group of people without the disease or the outcome measure being studied" (Schmidt & Brown, 2019, p. 209).  The cases are individuals with the disease or outcome measure, and the controls are individuals without the disease or outcome measure.  The purpose of a case-control study is to test whether there is an association between an exposure and a disease, condition or outcome measure (Schmidt & Brown, 2019, p. 209).
