Quizplus · Accepted Answer

Longitudinal studies follow the same group of individuals over a period of time, which increases the likelihood of selective attrition as participants may drop out due to death, illness, or other factors related to aging. This can lead to biased results if those who drop out are systematically different from those who remain in the study. Sequential studies also follow individuals over time but require multiple age groups to be studied simultaneously, while laboratory studies and observational studies do not involve following individuals over time.
