👉 PCT, or Probability of Correct Test, is a statistical measure used to evaluate the performance of a test or assessment by comparing the proportion of correct answers to the total number of questions. It's calculated as the ratio of the number of test-takers who answered a question correctly to the total number of questions attempted. A PCT of 0.80, for example, means that 80% of the test-takers answered the question correctly. This metric is particularly useful for comparing different tests or assessing the effectiveness of a test over time, as it normalizes results by the number of questions, providing a clear indication of accuracy relative to the test's scope.
