Quizplus · Accepted Answer

The weakness associated with cross-sectional studies is the inability to establish a temporal order of associated variables. Cross-sectional studies only measure exposure and outcome at a single point in time, which makes it difficult to determine if the exposure or the outcome occurred first. This makes it difficult to establish a cause and effect relationship between the two variables.
