A Stanine score is a way of representing a person's performance on a test using a single-digit scale ranging from 1 to 9. Each Stanine score represents a specific range of percentile ranks, making it easier to compare scores across different tests or groups.
Here's a breakdown of Stanine scores and their corresponding percentile ranks:
| Stanine | Percentile Rank |
|---|---|
| 1 | 1-4 |
| 2 | 5-11 |
| 3 | 12-23 |
| 4 | 24-38 |
| 5 | 39-56 |
| 6 | 57-71 |
| 7 | 72-84 |
| 8 | 85-94 |
| 9 | 95-99 |
Practical Insights:
- Stanine scores provide a standardized way to understand a person's relative performance compared to others who took the same test.
- They are particularly useful in educational settings for tracking student progress and identifying areas for improvement.
- Stanine scores can be used to compare performance across different subjects or tests, making it easier to identify strengths and weaknesses.
Examples:
- If a student scores a Stanine of 7 in reading, it means they performed in the 72nd to 84th percentile range, indicating above-average reading ability.
- A Stanine of 4 in math would suggest the student is performing in the 24th to 38th percentile range, indicating an average level of math skills.
Conclusion:
Stanine scores are a valuable tool for interpreting test results, allowing for a clear and simple representation of individual performance relative to a larger group. They provide a standardized way to compare scores across different tests and subjects, facilitating meaningful analysis and informed decision-making.
