A cohort study is a type of quantitative research. They are often described as "natural experiments" (Schmidt & Brown, 2019, p. 210). They are like case-control studies in reverse. In a cohort study, individuals are selected based on their exposure status. Researchers then investigate whether something individuals are exposed to is associated with the risk of a disease or condition (Schmidt & Brown, 2019, p. 210).
