Interpreting Your Grades

The Following Information may (depending on requirements and Availability):

Quiz N (where N is the number of the Quiz).

This is the RAW (not the percentage) score you received on the Quiz. The main reason I have listed the raw score is so that you can check to make sure I entered your grade correctly. To determine your actual score you should divide your score by the HIGHEST SCORE ATTAINED (found at the bottom of the listing) and multiple by 100. Remember, I curve each scoring item, so even if the Quiz was worth 50 points, but the highest score attained was 47 points, and you received a 41, you score is not 41/50 * 100 = 82, but rather 41/47 * 100 = 87.23. 

Quiz AVE (Your average quiz grade)

This will appear after the second quiz, and will be your true (percentage) quiz score. If there are only two quizzes, it will be the average of the two quizzes. If it appears after all three quizzes have been taken, it will be based on the average of the Best two of three quizzes taken.

Assign N (where N is the number of the Assignment).

As with the Quizzes This is the RAW (not the percentage) score you received on the Assignemnt. To determine your actual score you should divide your score by the HIGHEST SCORE ATTAINED (found at the bottom of the listing) and multiple by 100. 

Assign AVE (Your average Assignment  grade)

This will be your true (percentage) Assignment score. 

Project N (where N is the number of the Project).

As with the Quizzes This is the RAW (not the percentage) score you received on the Prokject. To determine your actual score you should divide your score by the HIGHEST SCORE ATTAINED (found at the bottom of the listing) and multiple by 100. 

Project AVE (Your average Project grade)

This will be your true (percentage) Project score. 

Final 

This is the RAW (not the percentage) score you received on the Final. To determine your actual score you should divide your score by the HIGHEST SCORE ATTAINED (found at the bottom of the listing) and multiple by 100. 

Average

This is your average (percentage) score to date. Until the very end, it is a little complicated to determine. At the very end of the semester it is calculated as:

Average Quiz Score * .50 + Average Assignment Score * .10 +
Average Project Score * .20 + Final Exam Score * .20 = Final Score

Until all components are in, your average score will be based on your score to date pro-rated by the percent of total components in. For example, suppose you  scored a 41 on the first quiz (the highest score attained was 47), and a 53 on the second quiz (the highest score attained was 74). That means that your quiz average (so far) is:

  (41/47 + 53/74)/2 * 100 =  (87.23 + 71.62)/2 * 100 = 1.59/2 * 100 = 79.43

Suppose also that you have completed all of the assignments, and your total score is 25 (out of 28), or 89.29.  Since we have only the quiz scores and Assignment scores to work with, we have only:

 .50 + .10 = .60 

percent of the total scores to work with. Therefore, your average score is: 

(Average Quiz Score * .50 + Average Assignment Score * .10)/.60 =
(79.43 *.50 + 89.29 *.10)/.60 = (39.76 + 8.93)/.60 = 48.69/.60 = 81.15

Z-Score

This is your Normalized score. It shows you how well you are doing relatively to the rest of your classmates. It is calculated as:

(Your Score - Class Average)/Class Standard Deviation

Basically, if your z-score is negative, you are below average for the class; If it is zero (0), you ARE the class average; If it is positive, you are above average. BY HOW MUCH?? If your z-score is -0.45, you are 0.45 Standard Deviations below the average; If your z-score is +1.32, you are 1.32 Standard Deviations above the average.

Rank

This is your Rank in the class, ranging from 1 (top of the class) to N (bottom of the class), where N is the number of students in the class.

Grade

Final Average Grade
90 - 100 A
80 - 89.99 B
70 - 79.99 C
60 - 69.99 D
< 60 F

This is your grade (to date, if the class is still going on). As already noted, it is based on the scheme to the left. As also previously noted, PLEASE do not come to me at the end of the semester and state "But I was only 1/2 Point away from the next highest letter grade". Because all evaluation components are curved, and only the best 2 of 3 quiz grades were counted, You really weren't.
