It is a mistake to believe that all graphs must go through the origin. ;/fkh0ylb2t h In physics many do not. But the scatter of the points suggests there are significant random errors. The fact that the line of best fi0/tfl 2hbk;yh t does not go through 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.
