See here for my standard response to such questions :-

The definitions I gave for Accuracy and Precision are the accepted ones in Engineering and especially Land
Surveying, thought you'd like to know. Think of a bell curve distribution, the closer the mean is to the
real value, the more accurate but the spread of the curve is the precision, the smaller the spread, the
more precise.

BTW my planet must be "JoHak", for Jo-Ann & Hakeeb.
My wife Jo-Ann is a Reservoir Engineer with AMOCO.
She's the brains in the family, so you guys got stuck with the dumb hick.
