A paired comparison is usually a method in which a certain employee, and his/ her job is compared with another employee of a similar post, and his/ her job. Usually, such paired comparisons are made on the grounds of the overall performance of an individual . Once the ratings are provided, the scores are derived by taking the mean and the standard deviation from all of the scores to come to a standard which would be used to measure all future comparisons.
