A research study in which different groups of people of different ages are compared to assess a particular variable is called a cross-sectional study. The study does not involve following people over time, but rather collecting data at one point in time from different age groups to compare their characteristics and behaviors. Longitudinal studies, on the other hand, involve following a group of people over an extended period to assess changes in a particular variable. Experimental studies involve manipulating variables to evaluate the effect on the outcome, while surveys involve collecting data through self-reported responses from individuals.
