Cross Sectional Studies
Cross-Sectional, Longitudinal, and Twin Studies
A cross-sectional study is a type of observational research that studies groups of subjects or populations at one particular point in time. The study, with participants who can be grouped by age or background, is beneficial because it not only can examine one variable, but it can examine additional variables simultaneously with only a slight, if any, cost increase. Another benefit of the cross-sectional research method is that it can be performed more quickly; however this information gathering method does not answer why questions or determine cause-and-effect relationships. One example of a cross-sectional study might be conducted to compare developmental milestones in two or more groups of children
