Quizplus · Accepted Answer

Both longitudinal and sequential designs involve following participants over an extended period of time. However, over time, participants may drop out of the study, leading to participant attrition. This can reduce the sample size and introduce bias into the results, limiting the generalizability of the findings. Therefore, participant attrition is a major limitation of both longitudinal and sequential designs.
