Answer: Discriminant validity
Explanation:
Discriminant Validity
Discriminant validity means a researcher needs to display or show that those variables that are not correlated are indeed not correlated in real life or practically .
For example the test above is measuring intelligence rather than reading ability so the researcher can use discriminant validity to actual show that reading ability is not related to intelligence and that the test is solely measuring intelligence.
He should show the evidence that there is really a low correlation between these two measures.
It is easier for psychologists to predict group behavior rather than individual behavior because individuals vary in their behavior whereas groups tend to display the same behavior.
The four primary goals of psychology are to describe, explain, predict, and change behavior.
Through describing the behavior of humans and other animals, we are better able to understand it and gain a better perspective on what is considered normal and abnormal. Psychologists are also interested in explaining behavior in addition to merely describing it. Why do people do the things they do? What factors contribute to development, personality, social behavior, and mental health problems? Psychologists make predictions about how we think and act. Once we understand more about what happens and why it happens, we can use that information to make predictions about when, why, and how it might happen again in the future. Psychology strives to change, influence, or control behavior to make constructive and lasting changes in people's lives.
