The line of best fit changes depending on the choice of independent variable, even for the same data. The quantity being minimized is different for the two cases. (sum of squares of vertical distances between the line and the data points vs. the same for the horizontal distance) The question is very specifically about the interpretation of the slope, and because the slope would be different for the other case, only one of the answers is correct. |
