Q

Classify the result below as an example of face validity, content validity, convergent and discriminant validity, or criterion validity:

A professor gives a class of 40 people his five-item measure of conscientiousness (e.g., “I get chores done right away,” “I follow a schedule,” “I do not make a mess of things”). Average scores are correlated (r = −.20) with how many times each student has been late to class during the semester.
