Question

Quizplus · Accepted Answer

Dr. Jackson is using a longitudinal study because he is following the same individuals (Lisa and Michael) over a long period of time and assessing them at multiple points in time. A cross-sectional study would involve assessing different individuals at one point in time, while an experimental study involves manipulating variables to determine cause-and-effect relationships. A sequential study involves both cross-sectional and longitudinal elements.
