So, in the set. 5 -1 6 -2 0 The highest number is 6 and the lowest number is - 2, so the range is: 6 - (-2) = 6 + 2 = 8 Think of it as the distance between 6 and - 2 on the number line, like this: ---|---|---|---|---|---|---|---|---|---|---|---|-- ... -3 -2 -1 0 1 2 3 4 5 6 7 8 ...
For the range as it pertains to functions, see range (mathematics) . In arithmetic, the range of a set of data is the difference between the largest and smallest values. However, in descriptive statistics, this concept of range has a more complex meaning.The range is the size of the smallest interval which contains all the data and provides an indication of statistical dispersion.It is measured in the same units as the data. Since it only depends on two of the observations, it is most useful in representing the dispersion of small data sets.owever, in descriptive statistics, this concept of range has a more complex meaning.
