Quizplus · Accepted Answer

In a cross-sectional study, individuals from different age groups are tested at the same time. The purpose of this study is to compare different age groups' performance on a specific task or test.

Standardized tests can also be used in cross-sectional studies, but they are not specific to this type of research design.
