Quizplus · Accepted Answer

The two main types of designs used in all research on human behavior are correlational and experimental. Correlational research investigates relationships between variables, while experimental research manipulates independent variables to examine their effects on dependent variables. Observational research can fall under either of these categories, as it can be used as a method of data collection in correlational or experimental studies. However, it is not considered one of the two main types of designs used in research on human behavior.
