Point Biserial (Item Analysis Statistic) The point biserial The point biserial correlation coefficient (PBCC) measures the correlation between the correct answer on an item and the total test score of a student. The point biserial identifies items that correctly discriminate between high and low groups, as defined by the test as a whole (as opposed to only the upper and lower 27% of a group). See Understanding Item Statistics Detail for details. correlation coefficient (PBCC) measures the correlation between the correct answer on an item and the total test score of a student. The point biserial identifies items that correctly discriminate between high and low groups, as defined by the test as a whole (as opposed to only the upper and lower 27% of a group). Generally, the higher the point biserial the better the item discrimination, and thus, the better the item. The following general criteria may be used to evaluate test items.
 * ===General Point Biserial Interpretation=== ||
 * .30 and above || Very good item ||
 * .20 to .29 || Reasonably good item ||
 * .09 to .19 || Marginal item; needs improvement ||
 * below .09 || Poor item; reject or improve ||
