The worker performing this job will need a keen background in statistics.
A five point rating system is to be used to indicate what a group of people think about the different items of a collection. Each item will gain a score of either 1, 2, 3, 4, or 5 from each rater in a group of raters.
This collection of ratings will need to be collapsed in a single, numeric value that will be either positive or negative. It will probably be an integral value, but could possibly be real.
Please see the attached document for a thorough description.
