Total Recall Is Never Absolute Precision
Be sure to understand the difference between the way the term percision and the term recall are used with respect to document review, especially predictive coding. Recall refers to the number of responsive documents that are identified by the document collection process. If you find 75,000 responsive documents out of a total of 100,000 responsive documents, the recall rate is 75%. If your collected data set includes the 75,000 responsive documents you found, and another 150,000 non-responsive documents, the precision rate is 50%.
