Measurements The "Best-Fit" Line The "best-fit" line is the straight line which passes as near to as many of the points as possible. By drawing such a line, we are attempting to minimise the effects of random errors in the measurements. For example, if our points look like this
our best-fit line should be as shown in the next diagram.
Notice that the best-fit line does not necessarily pass through any of the points plotted.
