This is simple logic. If 5 more prefer pizza than steak, you know 15 like pizza, and 10 like steak. 5p+?S=25. With p equaling how many liked pizza, and S equaling how many liked steak.
By checking to see if there is correlation, Sam is evaluating the criterion validity of the metric.
<h3>How to determine the measured parameter of the metric</h3>
From the question, we understand that Sam tests the metric to check for the presence or absence of correlation in the metric.
This, in other words means that Sam is checking the criterion validity of the metric.
Hence, the true statement is that Sam is evaluating the criterion validity of the metric.
