| 单词 | range |
| 释义 | range The difference between the largest and the smallest observed or possible values of a variable. The range can always be expressed in absolute terms: if the variable always has the same sign, it can also be expressed in relative terms, as the difference in the logarithms of the largest and smallest values. The range is not usually a good measure of dispersion, as it makes use of only two observations, which may each be outlier, that is, the result of freak events or statistical mistakes. |
