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.
The initial source of idea for the research is called the
world around. It means that the individual are likely to get the source of idea
from the environment or external factors that is used for the individual to
have an idea of what he or she is going to use for the research that he or she
is going to conduct.
