Quizplus · Accepted Answer

In a longitudinal study, participants of the same age are tested at multiple points in time, which allows researchers to observe developmental changes over time. Cross-sectional studies involve testing different age groups at one point in time, while experimental studies involve manipulating one variable to observe its effect on another variable. Sequential studies involve a combination of longitudinal and cross-sectional methods.
