Quizplus · Accepted Answer

Cohort effect refers to the impact of being part of a specific generation or cohort with distinct experiences or characteristics. In cross-sectional studies, different groups of participants are compared at the same time, and if these groups have different life experiences, it can create an artificial difference between them that is not solely due to the variable being measured. Therefore, option A is the correct choice. Options B, C, and D are not related to the concept of cohort effect.
