not sure if this had to do with math but my professor gave us this last hw assignment that i don't understand at all. It has to do with the grade scaling he does.
4x Exams = 37450
HW = 9362
Final = 16385
Lab = 23407
Recitation = 7022
Total Points = 93626
He asks whats the significance of this grade scale? The only hint was something about the multiplier. still confused.
The first obvious comparison to me is that homework counts about 10% of the total points.
Each of the four tests also count about 10%. Add those to the final, and the professor is counting over 50% of the grade on exams.
Another quarter of the grade is the lab.
You're in Chemistry with Prof. Kautz, right? Lol. :3
To understand the significance of the grade scale, let's break it down step by step.
First, we have the following components and their respective point values:
- 4x Exams: 37,450 points
- HW (Homework): 9,362 points
- Final: 16,385 points
- Lab: 23,407 points
- Recitation: 7,022 points
The total points available is 93,626.
Now, let's think about the concept of scaling the grades. Typically, when a professor scales grades, it means they adjust the scores to fit a desired range or distribution. It is done to ensure fair grading and sometimes to align with predetermined grade distributions or criteria.
In this case, the professor provided a hint about a "multiplier." Based on the information given, we can calculate the multiplier by dividing the total points earned (93,626) by the total points available (93,626).
Multiplier = Total Points Earned / Total Points Available
= 93,626 / 93,626
= 1
Now that we have the multiplier, we can use it to scale each component of the grade.
Scaled Exams = 4x Exams * Multiplier
= 37,450 * 1
= 37,450 points
Scaled HW = HW * Multiplier
= 9,362 * 1
= 9,362 points
Scaled Final = Final * Multiplier
= 16,385 * 1
= 16,385 points
Scaled Lab = Lab * Multiplier
= 23,407 * 1
= 23,407 points
Scaled Recitation = Recitation * Multiplier
= 7,022 * 1
= 7,022 points
By scaling each component of the grade by the multiplier of 1, we see that the scaled points are the same as the original points.
So, in this particular grade scale, the significance is that the professor is not adjusting the grades at all. The scaled points are identical to the original points. This means that each component's point value has equal weight in the final grade calculation.
It's important to note that this specific analysis assumes that the grading scale provided is the complete and accurate information. If there are additional components or factors not mentioned, the calculation and interpretation may change. It's always best to clarify with your professor if you have any doubts or questions about grading scales.
