Physics Experiment Linear Regression Issue

  1. Apr 29, 2012 #1
    1. The problem statement, all variables and given/known data

    Hello, I have done a laboratorial experiment (electron diffraction) and I've been doing the analysis of the obtained data.

    I have plotted the data obtained experimentally, and the slope of the obtained linear regression should give a certain value.

    What's happening is that the slope of the linear regression gives a value inferior to any of the individually calculated values, is this normal? and this value is quite different from the theoretically expected one, while all the individual values are much closer to the expected one. This is my only question.

    Thank you for your attention
