1 Draw the max line -- the one with as large a slope as you think reasonable (taking into account error bars), while still doing a fair job of representing all the data. Measure the slope of this line.  Calculate the uncertainty in the slope as one-half of the difference between max and min slopes.
Steps to calculate the percent error: 1  Subtract the accepted value from the experimental value. 2  Take the absolute value of step 1. 3  Divide that answer by the accepted value.4  Multiply that answer by 100 and add the % symbol to express the answer as a percentage.
