8.01 Weekly Quiz Results, Fall 1997

The average grade for all 8.01 students on the Weekly Quizzes was 75.6, which I think is very good.

The passing grade for the Weekly Quiz average has been set at 65.0, and other numerical grades can be translated into letter grades according to the following chart:

 NUMERICAL GRADE LETTER GRADE 89.0 - 100 A 77.0 - 88.9 B 65.0 - 76.9 C 53.0 - 64.9 D 0.0 - 52.9 F

A histogram of the grades is shown below:

In our effort to be as fair as possible, we are using a fairly complicated method of computing the weekly quiz average.

STEP 1: If you have taken all 9 of the Weekly Quizzes, then the lowest 2 grades will be dropped. Average the remaining 7, and call the result your "unrenormalized" quiz average. If you have any unexcused absences for the Weekly Quizzes, they count as quizzes taken with a grade of zero.

If you had excused absences from one or more of the 9 Weekly Quizzes, either because you entered the course after it started, or for any other reason, then the lowest 2/9 of your Weekly Quiz grades will be dropped. (That is, we didn't think it was fair to allow students who entered the course late to drop a larger fraction of their grades than the students who were here from the start.) A fraction of a quiz is "dropped" by counting it less in the average. For the precise formula, follow these links:

STEP 2: Since evidently not all instructors grade in the same way, we are "renormalizing" the Weekly Quiz averages to account for the differences as well as we can. For this purpose, each instructor has been assigned a renormalization factor Q, which is used to multiply the points that were taken off. That is,

To say it in a language that's sort of like an IRS form, you can compute your renormalized grade by the following steps:

2. Multiply the result by the factor Q appropriate to your instructor, obtained from the table below.
