NOTE: In reporting the averages from the test we drop the lowest scores. This is because 25% (2 out of 8) of all scores will eventually be dropped. In comparing your average with the class average you need to compare with an average which is representative of the final average. Dropping the lowest scores before reporting the average is one way of estimating the effect of the final drops. GBA 1st test 110 students took test 1 Multiple Choice 92 students earned 20 or more points for those 92 the average was 34.5 (57.5%) Problems 86 students earned 16 or more points for those 86 the average was 34.0 (52.3%) multiple choice grades problem grades 2nd test 107 students took test 2 Multiple Choice 82 students earned 30 or more points for those 82 the average was 40.6 (67.7%) Problems 84 students earned 21 or more points for those 84 the average was 39.8 (61.2%) multiple choice grades problem grades 3rd test 102 students took test 3 Multiple Choice 81 students earned 25 or more points for those 81 the average was 37.8 (63.0%) Problems 80 students earned 17 or more points for those 80 the average was 34.3 (52.8%) multiple choice grades problem grades 4th test 98 students took test 4 Multiple Choice 76 students earned 25 or more points for those 76 the average was 35.6 (59.3%) Problems 78 students earned 22 or more points for those 78 the average was 34.9 (53.7%) multiple choice grades problem grades Overall averages 95 students took all four tests for these 95 students the final HW average is 8.6 points the final quiz average is 7.6 points the final test average is 57.4% (45.9 points) and the overall average is 62.1 points Note that the overall average includes all students who took four tests. The test average is computed by dropping the lowest MC section and the lowest problem section for each student (except one section of test 4 must be kept), computing each student's average, and then computing a global average for all 76 students. With this final average, the final grade scale is 43.4 - 53.6 D 53.7 - 65.8 C 65.9 - 77.7 B with below 43.4 as E and above 77.7 as A. The final scale was selected so as to find gaps in the distribution. With the scale as given above the highest E is 42.3, the lowest D is 43.4, the the highest D is 52.7, the lowest C is 53.7, the highest C is 64.9, the lowest B is 65.9, the highest B is 77.0, and the lowest A is 77.8. The smallest gap is 0.8 points between B and A. Grades were assigned strictly based on this scale. Be sure to check your TA's computation of your final grade. If you find a significant error, please contact me or your TA. You may also collect your Test 4 by contacting your TA. Please note that I will be off campus until Monday Aug. 12.
