1.
A major disadvantage of the longitudinal method is:

b) The groups studied are too heterogeneous.
c) Subjects of the study drop out over time.
d) It cannot tell us about changes in individuals.
2.
For developmental researchers, a major disadvantage of the cross-sectional method is:

Explanation / Answer
1. C - If researched depends on only a particular group of subjects, over a course of time, the subjects may become unaivalable for the study due to change in contact, refusal, incapacity or even death, which resudes usable data to come to a conclusion.
2. C. Since two variables are measured at thesame time, it is impossible to determine a cause-effect relationship as well as to study the changes in individuals over a period of time.
3. C. For developmental research, sequesntial studies are the best as it allows the researcher to accurately measure changes more than any other type of study.
