This is transitivity in action it allows us to understand the wider web of relationships that exists between all options from just a handful of comparisons. Probabilistic Pairwise Comparison combines transitivity together with pattern recognition so that each participant only has to vote on a tiny sample just 10 to 20 pairs and then an algorithm analyzes the voting patterns over time to build a confidence model of how each opinion ranks in comparison to each other. Suppose Option1 wins: rating1 = rating1 + k(actual expected) = 1600+32(1 0.76) = 1607.68; rating2 = rating2 + k(actual expected) = 1400+32(0 0.24) = 1392.32; Suppose Option2 wins: rating1 = rating1 + k*(actual expected) = 1600+32(0 0.76) = 1575.68; rating2 = rating2 + k*(actual expected) = 1400+32(1 0.24) = 1424.32; To automate this process, check out our ELO Pairwise Calculator Spreadsheet Template (link coming soon, subscribe to our newsletter to be notified). If We want to analyze this structure, we have to prepare an AHP surveys, which is also well-known as pairwise comparison survey.

The Pareto Chart of Total shows which requirements were selected the most often. The column labeled MS stands for "Mean Square" and therefore the value \(2.6489\) in the "Error" row and the MS column is the "Mean Square Error" or MSE. The degrees of freedom is equal to the total number of observations minus the number of means. Using the filled-in matrix (on the far right above), count how many times each item is listed in the matrix, and record the totals in the ranking matrix (below).
