Quartile Range

Quartile Range

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

Notation

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.
