The range provides an indication of statistical ...

Feature scaling is used to bring all values into the range [0,1]. This is also called unity-based normalization. This can be generalized to restrict the range of values in the dataset between any arbitrary points and , using for example ′ = + ().
In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmax x i P(X = x i)). In other words, it is the value that is most likely to be sampled.

Ordered Data Set (of an even number of data points): 7, 15, 36, 39, 40, 41. The bold numbers (36, 39) are used to calculate the median as their average. As there are an even number of data points, the first three methods all give the same results.
