Percentage Discrepancy

  1. Sep 19, 2010 #1
    1. The problem statement, all variables and given/known data

    Hi guys, I need help with percentage discrepancy.

    2. Relevant equations

    I understand that percentage discrepancy is given by |observed value - measured value| /
    measured value x100%

    where || is the absolute value.

    3. The attempt at a solution

    However, one of my observed value is 0.000 and measure value is 0.0008
    Although the difference is very small, because of the zero observed value, my percentage discrepancy calculated to be 100%. Is there an assumption in the formula used that the observed value cannot be = to zero?

    Or should I keep percentage discrepancy to be 100% in this case?

    Thanks for the help.
