Final answer:
A suitable group for a cohort study, such as one on occupational risks, might involve battery workers. Cohorts consist of subjects with one or more shared characteristics who are followed over time, facilitating the study of how these characteristics relate to certain outcomes.
Step-by-step explanation:
A cohort study:
A suitable group for a sure-based cohort study can be selected from different populations depending on the study's objective. However, one such group could be certain occupational groups, like battery workers, that are exposed to specific risks or conditions relevant to the study. A cohort study typically involves a group with shared characteristics or experiences, tracked over time to observe the development of certain outcomes, such as diseases or the effects of exposures.
False, a cohort is not simply a group with different ages, weights, genders, and health statuses. It specifically refers to a group of subjects selected based on some shared characteristic, often before the development of the disease or outcome of interest. For example, the famous study by Doll and Hill followed a cohort of British male physicians to study the link between smoking and lung cancer, demonstrating how cohort studies can reveal vital epidemiological connections.
