A teacher wants to calculate a class average on the last test. One student made a significantly lower score than the rest of the
class because he failed to follow instructions. Which measure of center would be best for the teacher to use to get an accurate idea on how well the class as a whole performed on the last test? A. mode
B. median
C. mean
D. range
The answer is C. You would use MEAN because it gives you the average although it doesn't always have to be a whole number. Therefore despite that one student performing badly won't affect the rest of the class. Again hope this helps : )
