Averaged Sum of a Series of Numbers with Each Number Having a Specific
From Laurel Buehrig@21:1/5 to All on Fri Oct 7 08:06:02 2022
Let's say I need to add 5 different test scores in the area of math for a student, all of which are in a single column. Each score is put in as a raw number with a coordinating possible total score. The total student score column sums at the bottom and
the total possible score column sums at the bottom. I currently have the summed student scores being divided by the summed possible scores. However, in the instance that a student was either exempt or didn't take one of those 5 tests yet, the average
formula still includes the total possible score for the missing test. How can I build a formula that takes the missing test score's total possible out of that individual student's calculation?
Total Possible Student Score
1: 50 34
2: 80 ???
3. 100 79
4. 40 35
5. 50 50
6: SUM (320) SUM ( 198)
SUM formulas in row 6: =SUM(D1:D5) and =SUM(E1:E5), respectively
AVG formula: =AVG(E6/D6)
