Pretest &Post-test Score Results


      The pre-test and post-test are identical. They include 20 multiple-choice problems. The grades of both tests are out of 20. The y-axis of the first two graphs are percentages of students who've got the specific score. For example: in the first graph, there are 14% of students with a score of 11 out of 20. 

 

Note: the average score changes from 12.04 (pre-test) to 13.4 (post-test); the number of low-score students decreases (from 3% to 2%), while the number of high-score students increases (from 18% to 31%).
