IMO, the way the error bars combine is very intuitive. You are really just rounding to 6 or 12 sig-figs after every operation. People just seem to get really hung up on the point that error bars exist in the first place, and combine. I suspect it has a lot to do with the way that rounding is taught in school. It's absolutely hammered into use that you should never round until the very end, otherwise you lose precision. |
