I don´t understood what you mean, are you working with a index or are you trying
to ask us about (weights = pesos). Because if you are talking about weights, usually one is going to think about weighted averages and all that jazz.
Course grades: Many teachers will use a "weighted average" when calculating a student's grade in a course. For example, a teacher might say the test average is 60% of the grade, quiz average is 30% of the grade, and a project is 10% of the grade. Suppose Mary got 90 and 78 on the tests; 100, 100 and 85 on the quizzes; and an 81 on the project. Her course grade would be: Test average = (90 + 78)/ 2 = 84 Quiz average = (100 + 100 + 85)/3 = 95 Course grade = .60*84 + .30*95 + .10*81 = 87 Here, the tests carry a "weight" of .60 (or .30 each), the quizzes carry a "weight" of .30 (or .10 each), and the project carries a weight of .10. Note that the test average and the quiz average are not weighted averages, but the course grade is.
can you tell me how to calculate a weightee average for
the problem below.
subject max marks marks scored
maths 200 150 Science 100 50
To calculate the weighted average, you need to see which values are the 'weight' and 'score'
Now from the question, 200 and 100 are the weights. As for the score, they are 100 and 50.
Now you can calculate the weighted average by:
1. Multiply each score by its weight:
=> 200(150) + 100(50)
2. Multiply and add the above:
=> 30000 + 5000
3. Now, add all the weight to get the total weight.
=> 200 + 100 = 300
4. Divide the 35000 by the total weight
= 116.67 <--Answer
