Types of Research Methods in Surveys

The video tutorial explains the three main types of survey research: descriptive research, longitudinal studies, and evaluation research. Descriptive research collects data at a single point in time to estimate population parameters and make associations. Longitudinal studies examine the effects of situations over time, either through cohort or trend studies. Evaluation research assesses the impact of planned changes. Examples are provided for each type to illustrate their application. The tutorial concludes by revisiting the initial example and categorizing it as evaluation research.
