Hey, I have to use this today in my programming test, and I don't remember how to calculate a weighted average. Say there are 3 grades a Quiz, a Test, and Homework.
The test is weighted 60% of the grade, the homework is 20%, and the Quiz is 20% of the grade.
Say the grades for these are: 85, 70, 90
How would I calculate the weighted average? Any help extremely appreciated.
That's a purely statistical problem, not programming
Multiply each grade by its percentage.... then sum the results from all 3...
Test Weight: 60%
Score: 85
WS: 51
Hmk Weight: 20%
Score: 70
WS: 14
Qz Weight: 20%
Score: 90
WS: 18
Weighted Average: 51+14+18 = 83
I know that is not programming, but I have to assign costants and make that calculation in my program to be able to update the database I'm working with. I don't know why he couldn't just let us use a regular average. :)
How often is the simple answer the one desired?
Is there a complex version?
I have no doubt that, given a little time, there is always an answer to any question such that nobody, not even the person giving the answer can figure it out.:D
Stop screwing with me man... my head's hurtin...
