Depends entirely on the accuracy of the scale’s reporting device. If it’s 182 pounds and you are using a load cell that has a processor that gives you 10 digits of precision, then it’s 182.0000000000 pounds ~ so were you rounding off the readout from a digital scale or what?
But what you are assuming here is the whole point:
What if the measurements were made on all different scales at different times and at different places?
What is some of the weights were measured on a home scale from K-Mart, some were measured on a doctor’s office scale by the football players doing it themselves, and some were performed by high-accuracy laboratory scales?
Now you try to combine different measurements from different sources that are not consistent.
That’s the problem.
Climateers want to combine guess-timates from counting the entrails of lizards (counting bacteria in fossils), tree rings, and ice core samples, and then combine those with modern thermometers.
The result must necessarily be wildly inaccurate.
