Quartile Range

Quartile Range

Distance between the limits of a quartile in a statistical distribution.


We can note:

  • EQ1 = |Q1xmin|
  • EQ2 = |Q2 – Q1|
  • EQ3 = |Q3 – Q2|
  • EQ4 = |xmax – Q3|

where EQ1, for example, refers to the range of the first quartile, \(x_{min}\) refers to the lowest datum in the distribution and \(x_{max}\) refers to the highest datum in the distribution.
