Weekly Math Problem #76

Weighted Average. Sometimes, I find problems just by Googling a topic or question type. So, this time I recalled computing a weighted average/mean and wanted to see what worksheets were available. In my search results was a [Weighted Averages Worksheet] from WOU. I've chosen problem 1 from the worksheet.

To solve this week's problem in completion, you need to recall the following math skills:

Computing a weighted average is something that, I find, students don't know how to do. When they are looking at grading distribution from a syllabus for a course, they're, sometimes, not too sure how to compute it. Hopefully the solution below is helpful.

When computing a weighted average, you should convert the each percent to its decimal equivalent, before multiplying it by the score or the average score for the specific category.

Student X's grade, using all of the scores, works out to be about 82.2%.

Student X's grade, after dropping the missed homework assignment (grade of 0/10), works out to be about 87.5%--a 5.3% increase.

▪️ Have you ever calculated a weighted average before?

▪️ Did you get the same averages I got?
