Explain longitudinal and cross-sectional designs and present strengths and weaknesses for each.
What will be an ideal response?
The ideal answer should include:
1. Longitudinal designs obtain data from the same participants at two or more points in time, with researchers noting changes in the participants' behavior or test scores. Longitudinal designs are expensive to conduct, subject attrition may occur, and conclusions are correlational.
2. Cross-sectional designs study people of different ages at the same point in time. This is the most commonly used design. Cross-sectional designs do not allow for intraindividual comparisons.
