range
The set of output values of a function.
Range refers to the difference between the largest and smallest values in a data set. It provides an understanding of the spread of data or variability in a set of observations.
To calculate the range of a data set, you simply subtract the smallest value from the largest value. For instance, if the smallest value in a set of data is 5 and the largest value is 25, then the range would be 25 – 5 = 20.
The range is useful in describing the distribution of data, as well as identifying possible outliers, which are observations that differ significantly from other observations in the same data set. However, it is important to note that the range is sensitive to extreme values and may not be the best measure of variability for skewed data or when outliers are present.
