How to Use the Calculator
- Enter the size of your rating matrix (e.g., 3 for a 3x3 matrix) and click "Generate Matrix"
- Enter the ratings in the matrix cells. For example, in a 3x3 matrix, you might use ratings 1, 2, and 3
- Click "Calculate" to compute the percentage agreement
- The calculator will display the percentage agreement and an interpretation of the result
Understanding the Results
The Percentage Agreement is a measure of how much raters agree on their assessments. It is calculated as:
Percentage Agreement = (Number of agreements / Total number of ratings) × 100%
Interpretation Guidelines
- 90%+ Strong agreement
- 80%-89% Very good agreement
- 70%-79% Good agreement
- 60%-69% Moderate agreement
- 50%-59% Fair agreement
- <50% Poor agreement
When to Use This Calculator
This calculator is particularly useful in:
- Research studies where multiple raters assess the same items
- Educational settings for evaluating agreement between different instructors
- Healthcare for assessing agreement between different practitioners
- Quality control processes where consistency is important
