Compare and contrast correlational and experimental research.
What will be an ideal response?
In correlational research, the goal is to describe the strength of the relationship between two or more events or characteristics. The more strongly the two events are related or associated, the more effectively we can predict one event from the other. Correlation does not equal causation. If we want to know if one event causes another, we must look to the experimental design for answers. An experiment is a carefully regulated procedure in which one or more factors believed to influence the behavior being studied are manipulated, while all other factors are held constant.
