According to Thomas L. Saaty, the consistency ratio should be less or equal to 0.1. Notice that the reference is to "independent" pairwise comparisons. Business Performance Management Singapore, Subscribe to Newsfeed For this experiment, \(df = 136 - 4 = 132\). So if we need a measurement and p-value for a mean differences, we get that from the table of pairwise comparisons. In this method, each pair of candidates is compared, using all preferences to determine which of the two is more preferred. Therefore, \[dfe = N - k\], Compute \(MSE\) by dividing \(SSE\) by \(dfe\):\[MSE = \frac{SSE}{dfe}\]. 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). The criteria are the cost, safety, capacity and style of the car. 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.
