Question

Quizplus · Accepted Answer

Cross-sectional studies involve testing different age groups at the same point in time, whereas longitudinal studies involve testing the same group over an extended period of time and cohort studies follow a specific group over time based on a shared characteristic (such as birth year). Intelligence tests are a specific type of assessment and not a type of study design.
