Measures of spread (range and IQR)
Statistics
Univariate statistics

We can gain a better understanding of a data set by locating the middle or centre of the data and measuring the spread. Knowing one of these without the other is often of little use.
The range is one way to gain an idea about how spread out a data set is. The range of a data set is the difference between the maximum data value and the minimum data value.
