QUESTIONS AND ANSWERS 100% CORRECT
◉ Strength of longitudinal study. Answer: It reveals patterns of stability
and change over time and can clarify whether outcomes are due to
maturation/aging or personal traits.
◉ Limitation of longitudinal study. Answer: High cost, long duration,
participant attrition (dropouts), and risk that findings may be outdated by
the time the study ends.
◉ Cross-sectional study. Answer: A design that compares people of
different age groups at one point in time. Instead of tracking the same
individuals, it provides a snapshot of age-related differences.
◉ Strength of cross-sectional studies. Answer: Time-efficient, less
costly, and avoids long-term participant commitment.
◉ Limitation of cross-sectional studies. Answer: Cannot determine how
individuals change over time; differences may reflect cohort effects
(generation-specific influences) rather than development.
