    Robin,
        I'm sure others out here can explain it better than I can
bit it's a statisical method of obtaining an estimate for the overall
error in a mathematical function, when one or more components has a
measurement error ( i.e. +/-). Therefore the overall result will have an
error corresponding to the "propagate" of those individual errors.
    You could look up the chapters on Statistical Evaluation of Data
in Analytical Chemistry.An Introduction , by A.D. Skoog, F.J. Holler and
D.M West,  Saunders College Publishing.
    Good Luck!
