Statistics

Quartile Range

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

Notation

We can note:
  • EQ1 = |Q1 - xmin|
  • EQ2 = |Q2 - Q1|
  • EQ3 = |Q3 - Q2|
  • EQ4 = |xmax - Q3|
where EQ1, for example, refers to the range of the first quartile, [latex]x_{min}[/latex] refers to the lowest datum in the distribution and [latex]x_{max}[/latex] refers to the highest datum in the distribution.
