 Two quantities are reported below. The mean and the standard deviation for each section, and for the class as a whole. So if the mean is 10.3 and the standard deviation is 3.85, then 68 % of the students who took the exam have scores between 10.3-3.85 and 10.3+3.85 (that is between 6.45 and 14.15) and 95 % of the students are between 2.60 (10.3-2*3.85) and 18.0 (10.3+2*3.85)
