**Damon**, Wednesday, June 24, 2009 at 4:02amAdd them all and divide by 15 to find the mean.

Put them in ascending order.

The middle one is the median.

Usually median is more representative because one or a couple of very high or very low scores can distort the whole picture if the mean is used. In this case the 135 would tend to drag the mean down and that score might not be representative of the class as a whole. Perhaps that student missed some classes.
