It is a mistake to believe that all graphs must go through thg 2o mjgmh mi71t01q7qdm et;:n-fp5he origin. In physics many do not. But the scatter of the points suggests there are significant random errors. The fact that the line of best fit does not go thrtdg;hoj p7mfnht1-qm 2:q705 e1mgi mough the origin can only be taken of evidence of a systematic error only if there is good theoretical reason to believe that the line must go through the origin.
