**MathMate**, Wednesday, July 15, 2009 at 10:28pmOne of the properties of the mean is that all numbers of the data set contribute equally (have equal weight) to calculate the mean. Therefore it can be distorted or affected by extreme values, or noise, or errors.

I suppose that the last value you added was way off the other values.
