  "definition": "1. The spread from minimum to maximum values that an instrument is designed to measure.\n\n2. A measure of spread which gives the distance between the lowest and the highest values in a distribution; a statistic used primarily with interval-ratio variables.\n\n3. The geographic area in which a plant or animal lives.\n\n4. The difference between the maximum and minimum values of a set of values. When the number of values is small (i.e., eight or less), the range is a relatively sensitive (efficient) measure of variability. As the number of values increases above eight, the efficiency of the range (as an estimator of the variability) decreases rapidly. The range, or difference between two paired values, is of particular importance in air pollution measurement, since in many situations duplicate measurements are performed as part of the quality assurance program.\n\n5. The difference between the largest and smallest values in a measurement data set.\n\n6. In statistics, the difference between the largest and smallest values in a distribution. In common use, the span of values from smallest to largest.\n\n7. The difference between the minimum and the maximum of a set of values. {ORD} {OW/EAD} {OPP} {OW/TSC} {OAR/OAQPS} {OECA} {ORCR}\n\n8. The difference between the minimum and the maximum of a set of values. [ORD].\n\n9. The difference between the largest and smallest values in a measurement data set. [EPA 1997a]\n\n10. In statistics, the difference between the largest and smallest values in a distribution. In common use, the span of values from smallest to largest. [CDC 2005]\n\n11. Those lands on which the native or introduced vegetation (climax or natural potential plant community) is predominantly grasses, grasslike plants, forbs, or shrubs suitable for grazing or browsing use. Range includes natural grassland, savannas, many wetlands, some deserts, tundra, and certain forb and shrub communities.",
