WebKendall’s Tau = (C – D / C + D) Where C is the number of concordant pairs and D is the number of discordant pairs. Example Problem Sample Question: Two interviewers … WebDec 22, 2004 · Kendall's tau coefficient is a measure of concordance between two paired variables. Given the pairs ( Xi, Yi) and ( Xj, Yj ), then. with Nc and Nd denoting the number of concordant pairs and the number of discordant pairs, respectively, in the sample. Ties add 0.5 to both the concordant and discordant counts. startcallback

Kendall’s Tau Correlation Real Statistics Using Excel

WebKendall’s Tau = (C – D / C + D) Where C is the number of concordant pairs and D is the number of discordant pairs. Example Problem Sample Question: Two interviewers ranked 12 candidates (A through L) for a position. The results from most preferred to least preferred are: Interviewer 1: ABCDEFGHIJKL. Interviewer 2: ABDCFEHGJILK. WebKendall's tau-a is computed as \tau_a (C R) = \frac {P-Q} {\frac {1} {2} \cdot n \cdot (n-1)} τ a(C ∣R)= 21⋅n⋅(n−1)P −Q where P equals twice the number of concordances and Q twice the number of discordances. Its range is [-1, 1]. (Note that Kendall tau-a does not take into consideration any ties, which makes it unpractical.
