How to Calculate Test Accuracy
Test accuracy is the percentage of questions answered correctly.
Formula
Accuracy = (Correct Answers / Total Questions) x 100
This measures how precisely a student answers questions, focusing on quality rather than completion.
Exemplo Resolvido
A student answers 42 out of 50 questions correctly.
- Accuracy = (42 / 50) x 100 = 84%
- Incorrect answers = 50 - 42 = 8
- Error rate = (8 / 50) x 100 = 16%
