The following table shows the grades of students who supplied me with 3-, 4-, or 5-digit identification numbers for the purpose of posting grades anonymously.

The records are listed in alphabetical order by identification number. If some students declined to supply I.D. numbers, the mean, median, and average-deviation values reflect the grades of all students, not just those whose grades are shown. The mean grade for each column is computed by converting the letter grades to numbers according to the following scale,

• A+ = 4.19, A = 3.89, Añ = 3.69, Añ/B+ = 3.49
• B+ = 3.29, B = 2.99, Bñ = 2.69, Bñ/C+ = 2.49
• C+ = 2.29, C = 1.99, Cñ = 1.69, Cñ/D+ = 1.49
• D+ = 1.29, D = 0.99, Dñ = 0.69, Dñ/F+ = 0.49
• F+ = 0.29, F = 0

averaging the numbers, and converting the resulting numbers back to letter grades according to the following scale:

• 3.9 and above = A+
• 3.7ñ3.89 = A
• 3.3ñ3.69 = Añ
• 3ñ3.29 = B+
• 2.7ñ2.99 = B
• 2.3ñ2.69 = Bñ
• 2ñ2.29 = C+
• 1.7ñ1.99 = C
• 1.3ñ1.69 = Cñ
• 1ñ1.29 = D+
• 0.7ñ0.99 = D
• 0.3ñ0.69 = Dñ
• 0.15ñ0.29 = F+
• below 0.15 = F

The average-deviation value is in letter-grade increments. For example, an average deviation of 1.0 means that on average, individual studentsí grades were exactly a letter grade above or below the mean grade. Average deviation is essentially a measure of how widely distributed studentsí grades are, as opposed to being clustered together at the mean.
