Question

Quizplus · Accepted Answer

The two main designs used in all research on human behavior are correlational and experimental. Correlational studies examine the relationship between two or more variables, while experimental studies manipulate one variable and observe the effect on another, allowing researchers to draw conclusions about causality. Options A and D are incorrect because "coefficient" and "field experiments" are not designs but rather additional methods or environments that can be used in correlational and experimental research. Option C is incorrect because "dependent" and "independent" refer to variables, not designs.
