1) Most of (micro-)benchmarking in computing. Of course you want a tiny bit more analysis in that case. 2) Slightly more real-world: Measuring things when you only have approximate rulers, have difficult things to measure (odd surfaces, etc.), or have to calculate from 2nd hand measurements (pictures with rulers, etc.) Not sure if that qualifies as Real World, but...?
