Cross sequential study example. A researcher might collect cross-sectional data on past smoking habits and current diagnoses of lung cancer for example. You first conduct a cross-sectional study with a sample of diabetes patients to see if there are differences in health outcomes like weight or blood sugar in those who follow a low-carb diet.
