Homework Help: Statistics

Posted by Avril on Tuesday, September 8, 2009 at 3:48pm.

My teacher is averaging up our grades in one area instead of including them all on our report card. For example, he is putting in one grade for the tests (the average of the grades) instead of including each individual grade for all of the tests. Are these two the same thing, or will they have different results?

What you will need to do is figure out what the average means, as a letter grade. Does it matter whether I say:
1) 5, 10, 3, 2, 7 (assuming each quiz is worth 10 points(
or
2) 27/50 ?

The total grade on a 100% scale would be 54% and that is an F in most grade books. In other words, it is the total number of points that is important.

Here is a good explanation of a GPA (Grade Point Average):
