Creation of the POP scores
The POP score methodology was developed by Don Levy, PhD at Sienna College Research Institute.

An example of a POP score calculation is as follows:

Goal: Create a summary for a set of 4 items (very unlikely = 0, somewhat unlikely: 1, somewhat likely: 2, very likely: 3), with values of 0-3 each; Approach: 1. Sum the points for all 4 items, total is 0-12 for each person, 2. Sum the totals for all respondents and divide by the maximum total
