Answer: This is an example of "CRITERION VALIDITY"
Explanation: Criterion validity is the extent or level in which a chosen measure is related to an observed outcome.
Extroversion is the chosen measure that is been correlated with conversation which is an observed outcome. This validity helps to know the extent in which the measure is related with the outcome.
