Observed range
Also: sample range
The interval from the smallest to largest value actually observed in a dataset.
Range summarizes extremes in the sample but is sensitive to sample count and is not a guaranteed population bound.
- Units
- same as observation
- Formula
range = max − min
Example Five times from 108 to 115 ms have an observed range width of 7 ms.
Common misconception Observed minimum and maximum are not absolute future limits.
