How do you count Uncertainty Measurement using Precision Error and Bias Error?

  1. Sep 29, 2010 #1
    1. The problem statement, all variables and given/known data

    Find the Uncertainty Measurement using Precision Error and Bias Error?

    The Length of line is 5.625 in. Precision Error is 0.13 in. Bias Error is -0.115 in. What is the UNCERTAINTY measurement?

    2. Relevant equations


    3. The attempt at a solution

    Please help!

    I understand what uncertainty measurement is but I don't know how to calculate it using Precision Error and Bias Error. It is my understanding that the Uncertainty in a standard Inches scale should be (1/8) / 2 = 1/16 inch. But its not true in this case............right?
