In a short essay, describe how multiperson comparison is done

What will be an ideal response?

Answer: Group-order ranking requires the appraiser to rank a group in terms of quartiles, quintiles, or some other fractional measure. In a group of 40, an appraiser might divide the group into quintiles: the top fifth, the second fifth, and so on.

Individual ranking is a top-to-bottom ranking of all individuals in a group. No ties are allowed, meaning that in a group of 40, individuals are ranked from 1 to 40.

Paired comparison involves pairing individual match-ups of employees. In a group of four employees, A, B, C, and D, for example, A might first be matched against B. Either A or B would be judged the "winner," then A would be matched against C and the process repeated. All combinations of pairs would eventually be generated, resulting in a head-to-head ranking of all employees. Clearly, this method reveals a wealth of data–but it should also be clear that with large groups of employees it can be extremely time-consuming.
