Taking a series of observations with random error, isn't the size of the average related to the volume? Given enough data the average error, if random, should trend towards zero? The average seems to tell us little except that a great number of sights have been considered. And that there does not seem to be significant systematic error. It would seem that the more important indicator here is the standard deviation. It would seem to indicate significant random error. --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to NavList@fer3.com To , send email to NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
