85, suggesting a strong relationship between the rankings. Step 5: Insert the totals into the formula: Step 4: Sum the values in the two columns: The number of discordant pairs is similar to Step 2, only you’re looking for smaller ranks, not larger ones. Step 3: Count the number of discordant pairs and insert them into the next column. When all concordant pairs have been counted, it looks like this: However, going down the list to the third row (a rank of 4), the rank immediately below (3) is smaller, so it doesn’t count for a concordant pair. For example, the first rank in the second interviewer’s column is a “1”, so all 11 ranks below it are larger. Concordant pairs are how many larger ranks are below a certain rank.

Step 2: Count the number of concordant pairs, using the second column. The rankings for Interviewer 1 should be in ascending order (from least to greatest). The first column, “Candidate” is optional and for reference only. The results from most preferred to least preferred are: Sample Question: Two interviewers ranked 12 candidates (A through L) for a position. Where C is the number of concordant pairs and D is the number of discordant pairs. Most statistical packages have Tau-B built in, but you can use the following formula to calculate it by hand: For square tables, Tau-B and Tau-C are essentially the same. Tau-C is usually used for rectangular tables.Tau-A and Tau-B are usually used for square tables (with equal columns and rows).Unlike a linear graph, a negative relationship doesn’t mean much with ranked columns (other than you perhaps switched the columns around), so just remove the negative sign when you’re interpreting Tau. A quirk of this test is that it can also produce negative values (i.e.
