+8262 The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9-3 = 6. It is that simple! But perhaps too simple ... The Range Can Be Misleading The range can sometimes be misleading when there are extremely high or low values. Example: In {8, 11, 5, 9, 7, 6, 3616}: the lowest value is 5, and the highest is 3616, So the range is 3616-5 = 3611. The single value of 3616 makes the range large, but most values are around 10. So you may be better off using Interquartile Range or Standard Deviation. Range of a Function Range can also mean all the output values of a function, see Domain, Range and Codomain.
