本题详细解析:
It is a mistake to believc(tcl9(3vy uf e that all graphs must go through the 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 guf9clyc(3 (t vo 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.
