What does a cohort typically refer to in research contexts?

• A. A specific event in history
• B. A group of participants sharing a common characteristic
• C. An analysis of social behaviors
• D. A measurement of psychological variables

Answer: (B)

In research contexts, a cohort generally refers to a group of participants who share a common characteristic or experience, often defined by a specific time frame, such as age, exposure to a particular treatment, or an event that happens in a given period. This grouping allows researchers to study the effects and outcomes related to the shared characteristic over time, facilitating comparisons both within the cohort and against other groups. For example, in medical research, a cohort might consist of individuals who all underwent the same type of surgical procedure within a particular year. By studying this cohort, researchers can gain insights into the long-term effects of that surgical procedure or the recovery rates specific to that demographic. This term is distinct from other options, which focus on broader or different aspects of research but do not accurately capture the idea of a cohort as a defined group with a shared characteristic.
