1. What is the Q Score?

The Q Score is a simple metric that calculates the ratio of correct answers to total questions or items. It provides a standardized measure of performance or accuracy.

2. How Does the Calculator Work?

The calculator uses the Q Score formula:

Where:

• \( \text{sum correct} \) — Number of correct answers or items (unitless)
• \( \text{total} \) — Total number of questions or items (unitless)

Explanation: The equation calculates the proportion of correct responses, providing a score between 0 and 1 where higher values indicate better performance.

3. Importance of Q Score Calculation

Details: The Q Score is widely used in educational testing, quality assessment, research studies, and performance evaluation to quantify accuracy and measure outcomes.

4. Using the Calculator

Tips: Enter the number of correct answers and the total number of items. Both values must be valid integers (sum correct ≥ 0, total ≥ 1, and sum correct ≤ total).

5. Frequently Asked Questions (FAQ)

Q1: What does a Q Score of 1 mean?
A: A Q Score of 1 indicates perfect performance, meaning all answers or items were correct.

Q2: How is Q Score different from percentage?
A: Q Score is essentially the same as a decimal percentage (e.g., 0.75 Q Score = 75%), but expressed as a decimal value between 0 and 1.

Q3: Can Q Score be greater than 1?
A: No, Q Score cannot exceed 1 since the number of correct answers cannot exceed the total number of items.

Q4: What are typical applications of Q Score?
A: Q Score is commonly used in test scoring, survey analysis, quality control, research studies, and any situation requiring performance measurement.

Q5: How should I interpret a Q Score of 0.5?
A: A Q Score of 0.5 indicates that half of the answers or items were correct, representing average or moderate performance.
