This document contains formulas for calculating statistics from student grade data including the quantitative and qualitative averages, letter grade equivalencies, maximum and minimum grades, most common grade, median grade, and counts of students receiving each letter grade. The formulas use cell ranges to pull data from and perform calculations on numbers in columns H through J to analyze the grades of students listed from rows 6 to 15.
