In statistics, a measure of dispersion in a frequency distribution, equaling the difference between the largest and smallest values of the variable. The range is sensitive to extreme values in the sense that it will give a distorted picture of the dispersion if one measurement is unusually large or small. The interquartile range is often preferred.
In physical geography, a line of mountains (such as the Alps or Himalayas). In human geography, the distance that people are prepared to travel (often to a central place) to obtain various goods or services. In mathematics, the range of a set of numbers is the difference between the largest and the smallest number; for example, 5, 8, 2, 9, 4 = 9 - 2 = 7; this sense is used in terms like “tidal range” and “temperature range”. Range is also a name for an open piece of land where cattle are ranched.
1. A block of cells selected for similar treatment in a spreadsheet. A range of cells can extend across a row, down a column, or over a combination of the two, but all cells in the range must be contiguous, sharing at least one common border. Ranges allow the user to affect many cells with a single command—for example, to format them similarly, enter the same data into all of them, give them a name in common and treat them as a unit, or select and incorporate them into a formula.
2. In more general usage, the spread between specified low and high values. Range checking is an important method of validating data entered into an application.
