Question
Assume you are a manager of a restaurant that had 60 waiters/servers and you used the paired comparison technique to evaluate the performance of these waiters/servers on various dimensions. Now, for one of the performance dimensions (e.g., being a team player), you proceed to make paired comparisons. For example, Mary is better than John. Mary is better than Mark. Joe is better than Mary and so forth. How many paired comparisons would you have to make?Assume you are a manager of a restaurant that had 60 waiters/servers and you used the paired comparison technique to evaluate the performance of these waiters/servers on various dimensions.

Explanation / Answer
The pair comparison method requires the formula N(N-1)/2.
Here, N is the total number of employees. In this case waiters.
N(N-1)/2
60(60-1)/2
=60(59)/2
=3540/2
=1770
So, there will have to be 1770 paired comparisons.
