The Pairwise Comparison Matrix and Points Tally will populate automatically. Evaluation of preferences for alternatives based on their pairwise comparisons is a widely accepted approach in decision making, when direct assessment of the preferences is infeasible or impossible [1,2,3,4].The approach uses the results of pairwise comparisons of alternatives on an appropriate scale, given in the form of a pairwise comparison matrix.

The three judgments with highest inconsistency will be highlighted,with the last column showing the recommended judgment for lowest consistency ratio. Rather than asking participants to vote on every possible head-to-head comparison, probabilistic pairwise comparison asks for a much smaller sample of pair votes and uses data science techniques to predict the answer that would have been given for the pairs that didnt get voted on. Using OpinionX to stack rank his customers needs and then filter the results into different segments based on the number of gyms managed by each survey participant, Francisco was able to see which was the top problem for each of Glofoxs customer segments. (Ranking Candidate X higher can only help X in pairwise comparisons.) This test allows checking the inconsistencies which could be entered in the comparison tables. If youre working with larger option sets or participant populations and still need to do calculations manually, I would recommend using an ELO Rating Algorithm. Drafting these seeded options is no easy task. You can calculate the total number of pairwise comparisons using a simple formula: n(n-1)/2, where n is the number of options.
