The criterion cost is divided into subcriteria which are the purchase price, the fuel cost, the maintenance, and resale. 'Pairwise Won-Loss Pct.' ; If the overall p-value of the ANOVA is less than a certain significance level (e.g. ^ Example of Pairwise Comparison results from a Stack Ranking Survey on OpinionX, Stack ranking surveys use a more complex set of algorithms than the previously mentioned ELO Rating System to select which options to compare in head-to-head votes, analyze the voting to identify consistency patterns, and then combine that pattern recognition with the outcome of each pair vote to score and rank the priority of every option. Based on these priorities, it is the car Element which seems to answer the problem. In this example, it is the cost criterion that impacts the most the decision making, and in particular the subcriterion purchase price. History. Pairwise comparison of the criteria. The AHP online calculator is part of BPMSGs free web-based AHP online system AHP-OS. For example, these results appear to indicate that, This apparent contradiction is avoided if you are careful not to accept the null hypothesis when you fail to reject it. When that simulation was completed -- playing out the six conference tournaments -- a Pairwise was calculated based upon those results. If we had three conditions, this would work out as 3(3-1)/2 = 3, and these pairwise comparisons would be Gap 1 vs .Gap 2, Gap 1 vs. Gap 3, and Gap 2 vs. Grp3.
