Calculation deviations between experimental and computed data

    Hi, I need a help. Two questions I need to solve.

    1. What should I do to compare the difference between experimental and computed data. Let say I have 10 experimentally measured point and 10 computed points, and I need to compare the difference between them both.

    2.  What should I do to compare the difference between the plot of experimental data and plot of fit function (y=pxn/(1-xn)), where 'n' and 'p' are fitting parameters?

    Please help me.

    To compute the difference between theoretical and experimental points, I'd use this equation:

    %dev = [ (experimental - theoretical) / experimental] * 100


    Do this for each point.  For example,:

    %dev #1 = [ (exper#1 - theor#1) / exper#1]  * 100
    %dev#2 = [ (exper#2 - theor#2) / exper#2 ] * 100
