if the lecture grade is the mastering points worth 20% and exams worth 80%. what is the lecture grade?
mastering points: 1513
exam grades: 92,83,76,95,95
thank you!
LG = (1513 * 0.2) + ((92 + 83 + 76 + 95 + 95) * 0.8)
it comes out to be 655.4 so would it just be a 65.54?
Depends on how your particular professor grades.
Does he/she grade on total points or does he/she use a proportional scaling method to fit a perfect score into, say, 100 points.
It appears that there is no scaling used, since a perfect score on the mastering points is obviously above 100.
So I would say 655.4.
To calculate the lecture grade in this scenario, we need to first determine the weighted average of the mastering points and the exam grades.
Step 1: Calculate the weighted average of the mastering points:
The mastering points are worth 20% of the overall lecture grade. To calculate their contribution, multiply the mastering points by 20% (or 0.20):
Mastering points contribution = 1513 * 0.20 = 302.6
Step 2: Calculate the weighted average of the exam grades:
The exam grades are worth 80% of the overall lecture grade. To calculate their contribution, find the average of the exam grades and multiply it by 80% (or 0.80):
Exam grades average = (92 + 83 + 76 + 95 + 95) / 5 = 88.2
Exam grades contribution = 88.2 * 0.80 = 70.56
Step 3: Calculate the lecture grade:
Add the contributions from the mastering points and the exam grades together:
Lecture grade = Mastering points contribution + Exam grades contribution = 302.6 + 70.56 = 373.16
Therefore, the lecture grade is 373.16.
