What are the relative weaknesses and strengths of descriptive/correlational research compared to experimental research? Under what conditions would a psychologist choose one method as opposed to the other?
What will be an ideal response?
Experimental research is the more powerful of the two methods, in that it allows precise control over the independent variable and therefore yields cause-and-effect conclusions. On the other hand, experiments may be somewhat artificial and often cannot be done for ethical reasons. Descriptive/correlational studies are conducted in the subjects' natural environment, they are easier and faster to do than experiments, and they can be done ethically in many circumstances in which experiments cannot. However, the researcher has little control over extraneous variables, so cause-and-effect conclusions cannot be drawn. The choice between the two methods is a function of practical and ethical considerations.
