Answer to Question 1

F

Answer to Question 2

Longitudinal studies examine longer-range development of a group of individuals over time. They may have selective dropout or death of subjects and cost more time and money than other methods. Cross-sectional studies compare different groups of individuals at the same time on one occasion. Many find that groups have different experiences based on when they were born, so cohort effect may be problematic. Cross-sequential studies require less time overall than longitudinal studies, since they compare different groups of individuals over a shorter period of time and can make time-lag comparisons. Cross-sequential studies avoid the cohort effect, since they compare more than one group (cohort) with each other and over time.
