This file contains class distributions for all quizzes and exams, starting with quiz 1. Two graphs will be posted for each quiz/exam. The first graph contains a histogram that shows the range of scores and the number of students who obtained each score. This file also contains the mean or average score of the entire class. For example, on quiz 1, the individual scores ranged from 9 to 15. Three students obtained a score of 9, while 51 students obtained a score of 15. The second graph contains a histogram that shows the number of students who obtained correct responses on each of the test items. For example, test item 2 was answered correctly by 80 of the 105 students who took the quiz, while question 13 was answered correctly by all 105 students.
