accuracy rate
How often right
Accuracy rate is a measure of how often something is correct—typically expressed as a percentage.
It quantifies reliability in contexts like medical testing, data entry, or machine learning: The model achieved a 94% accuracy rate on the test data.
The phrase is somewhat redundant, since accuracy alone often implies a rate, but the full form emphasizes measurement.
