Learn how to use the Concordance Rate Calculator calculator and its working principles
The concordance rate is a measure of agreement between two diagnostic tests or assessments. It is calculated as the proportion of agreements divided by the total number of pairs, excluding pairs where both values are missing. A concordance rate of 1 indicates perfect agreement, while a rate of 0 indicates no agreement.

And Test 2 results are: 1, 1, 1, 0
The concordance rate would be calculated as follows:
