## Scaling (Curving) Grades Calculator Formula

The Scaling (Curving) Grades Calculator does not follow a specific formula but rather employs various scaling methods to adjust the grades based on the desired scale and curve value. Here's an overview of the process:

• Determine the minimum, maximum, and average grades from the original grades.
• Calculate a multiplier based on the desired scale and curve value.
• Apply the scaling method to each original grade, multiplying it by the multiplier.
• Round the curved grades to an appropriate precision.

## Illustrative Example

Let's consider an example to illustrate the functionality of the Scaling (Curving) Grades Calculator.

Suppose you have the following original grades: 75, 80, 90, 65, and 85. You want to adjust these grades based on a desired scale of B (80-89) using the linear scaling method and a curve value of 5%. After inputting the values and submitting the form, you would obtain the following result:

• Original Grades: 75, 80, 90, 65, 85
• Desired Scale: B
• Scaling Method: Linear
• Curve Value: 5%
• Curved Grades: 77.5, 82.5, 90.0, 72.5, 85.0

The calculator adjusts each grade proportionally, ensuring the desired scale is achieved while considering the specified curve value.
