A True Negative Classification is a binary classifier negative prediction that a correct class prediction.

**AKA:**TN Outcome.**Context:**- It can be a member of a True Negative Classification Set (to calculate a true negative error rate).

If the instance is negative and it is classified as negative, it is counted as a*true negative*; if it is classified as positive, it is counted as a*false positive*. Given a classifier and a set of instances (the test set), a two-by-two*confusion matrix*(also called a contingency table) can be constructed representing the dispositions of the set of instances.
