Automated Student Grade Normalization
=ROUND((B2-MIN($B$2:$B$31))/(MAX($B$2:$B$31)-MIN($B$2:$B$31))*100,2)ADVERTISEMENT - IN-ARTICLE
Implementation Guide
This task allows teachers to normalize student scores onto a 0–100 scale, ensuring fair comparison across exams of varying difficulty. By using MIN and MAX functions, the formula dynamically adjusts as new grades are entered. It is particularly useful for large classes or multi-section courses where consistency is critical. The approach is transparent and easy to explain to students and administrators. Teachers can further map normalized scores to letter grades using LOOKUP or IFS. This method reduces grading bias while maintaining academic rigor and documentation quality.
