Max is a graduate student who wants to determine the relation between identity formation and the environment. To do so, he interviews a group of 5-year-olds, a group of 10-year-olds, and a group of 15-year-olds and asks them what they plan to do when they finish school. In this example, Mark is using a research method.

Cross-Sectional Research Method

Explanation:

Cross-Sectional Research Method often referred to as cross-sectional analysis, is a form of research study, in which the researcher gather data to make deductions about subjects or population of interest at a particular point in time. It is conducted such that, a researcher might gather data from selected groups of different age, class or level at one point in time. Thus, deductions or inferences can be made based on the age, class or level differences rather than things that occurred over a time.

Hence, Max is considered to be using Cross-sectional research method, since he is using population of different groups based on age to conduct research or gather information.
