Accuracy Percentage vs Correct Answers
公式
## 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.
计算示例
A student answers 42 out of 50 questions correctly.
- 01Accuracy = (42 / 50) x 100 = 84%
- 02Incorrect answers = 50 - 42 = 8
- 03Error rate = (8 / 50) x 100 = 16%
