What is a Square Root Curve Calculator?
A square root curve calculator is an educational tool that applies the square root grading method to transform raw test scores into curved grades. This mathematical approach takes the square root of the original percentage score and multiplies it by 10 to create a more favorable grade distribution.
The square root curve calculator is particularly effective for difficult exams where traditional grading might result in discouraging low scores. By using this curve method, educators can maintain academic standards while providing students with grades that better reflect their relative performance.
How Does the Square Root Curve Calculator Work?
Mathematical Formula
Curved Score = √(Original Score) × 10
The square root curve calculator applies this simple yet effective formula to transform scores, providing significant improvement for lower scores while maintaining reasonable adjustments for higher scores.
