Re: Trouble with "flexure of beams" apparatus

once you have an estimate for the correct value, plug
_all_ the measured points into the equation and see how much scatter there is.

Let me clarify that:

Make a scatter plot: observed deflection versus predicted deflection. If
all the points lie on the same diagonal line, all is well. If they fall
into groups on N different diagonals, then at least N-1 of the groups is
messed up. Retake a data point from each group.

Also: Is there any chance that the beam in this experiment is rectangular,
and was oriented in "portrait mode" for some runs, and "landscape mode" for
other runs?
