本题详细解析:
It is a mistake to believ:iw alxv66u5xt q dq--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 fat w6qu-6l:5xqxad i-vct that the line of best fit 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.
