Oscilloscopes can also be used to measure voltages, often in excess of 100V, so in the spirit of those extremely unlikely "explanations" that show up in the explainxkcd tables, I offer this.
PS this story doesn't make sense because you can tell when a voltmeter is out of range.
- aix1 4y ago> PS this story doesn't make sense because you can tell when a voltmeter is out of range. It's also a bit sloppy with the bounds. To me, "reads only as far as 100" includes 100V, whereas the measured voltages only go as high as 99V.
- whatshisface 4y agoWhile we're complaining, you can't measure the "voltage" of an electron tube out of circuit.
- ilyt 4y agoSure you can, just buy a SMU (source measurement unit, few multimeters cobbled together with 4 quadrant power supply)
- YetAnotherNick 4y agoI think the point is that the sample readings were in the range of voltmeter, but if some sample crossed 100V it would show as 100V in the voltmeter. So even though no sample crossed 100V, the data is clipped still.
- whatshisface 4y agoThat's not good statistics - just because the precision of measurements falls off sharply at 100V doesn't mean that out-of-range readings aren't valid measurements.
- YetAnotherNick 4y agoAssume we got one out of range measurement out of 100. We can't say anything about variance of reading if we don't have any prior on variance ie using bayesian statistics. That's the joke that traditional statistician can't figure out the obvious thing.
