Scaling (Curving) Grades Calculator
Multiply the original grade by 100 and divide by the maximum grade to find the scaled grade.
The Scaling (Curving) Grades Calculator helps educators and students adjust grades to a consistent and fair scale. Whether addressing uneven test difficulty or normalizing scores, this tool ensures that grades are scaled proportionally. It is widely used in academic settings to maintain fairness and motivate better performance.
Formula
SG = OG × (100 / MG)
| Variable | Description |
|---|---|
| SG | Scaled grade |
| OG | Original grade |
| MG | Maximum grade achieved in the test or exam |
Solved Calculations
Example 1: Scaling a Grade of 85 When the Maximum Grade is 95
| Step | Value |
|---|---|
| Original Grade (OG) | 85 |
| Maximum Grade (MG) | 95 |
| Scaled Grade (SG) | 85 × (100 / 95) = 89.47 |
Example 2: Scaling a Grade of 72 When the Maximum Grade is 90
| Step | Value |
|---|---|
| Original Grade (OG) | 72 |
| Maximum Grade (MG) | 90 |
| Scaled Grade (SG) | 72 × (100 / 90) = 80.00 |
What is Scaling (Curving) Grades Calculator?
The Scaling (Curving) Grades Calculator is an efficient tool that adjusts grades based on a predetermined distribution or scaling method.
It is often used by teachers, professors, and academic institutions to normalize grades, ensuring fairness when evaluating students’ performance.
By applying a curve, grades are adjusted relative to the highest score or based on statistical measures like mean and standard deviation.
For example, in a bell curve distribution, the average score typically centers the curve, while lower and higher scores are proportionally adjusted. This calculator simplifies the process by automating these adjustments and providing precise scaled grades.
For instance, if the class average is 72% and the highest score is 95%, the calculator can scale the grades to improve fairness, particularly in challenging exams.
It also supports different grading schemes, such as linear transformations or bell curve adjustments, making it versatile for various academic needs.
Final Words:
In essence, the Scaling (Curving) Grades Calculator is a valuable tool for promoting fairness and accuracy in academic evaluations. It simplifies complex scaling processes, ensuring that every student’s performance is assessed equitably.
