A cross-sectional research design involves collecting data from different groups of participants at the same time, which is what Mark is doing by interviewing the different age groups. Longitudinal research design involves studying the same participants over a period of time, which is not the case here. Confounded research design involves a flaw in the study where the results may be affected by an external variable, which is not mentioned here. Multifactor research design involves manipulating and studying multiple independent variables, which is also not mentioned here.
