Some teachers use a weighted mean to calculate gradesEach score is assigned a weight based on its importanceTo find a weighted mean, each score by and Reports For example, a student's chemistry grade based on four sources40% from lab reports10% from quizzes 25from the midterm examand 25% from the 90 What is the student's weighted mean given the scores in the table Exam Final Exam The weighted score your answerType an integer a
To calculate the student's weighted mean, you need to multiply each score by its corresponding weight and then add up all the weighted scores.
Here are the scores and weights given in the table:
- Lab Reports: 40% (weight)
- Quizzes: 10% (weight)
- Midterm Exam: 25% (weight)
- Final Exam: 25% (weight)
Let's denote the scores as follows:
- Lab Reports score: L
- Quizzes score: Q
- Midterm Exam score: M
- Final Exam score: F
To find the weighted mean, you need to calculate the weighted score for each component and sum them up.
Weighted score for Lab Reports = L * 0.40
Weighted score for Quizzes = Q * 0.10
Weighted score for Midterm Exam = M * 0.25
Weighted score for Final Exam = F * 0.25
Now, you can calculate the weighted mean by summing up all the weighted scores:
Weighted Mean = (Weighted score for Lab Reports) + (Weighted score for Quizzes) + (Weighted score for Midterm Exam) + (Weighted score for Final Exam)
So, the formula for the weighted mean is:
Weighted Mean = (L * 0.40) + (Q * 0.10) + (M * 0.25) + (F * 0.25)
Please provide the values of L, Q, M, and F (the scores) in order to calculate the weighted mean.
