Step-by-step explanation:
The Quartile Deviation(QD) is the product of half of the difference between the upper and lower quartiles. Mathematically we can define as: Quartile Deviation = (Q3 – Q1) / 2. Quartile Deviation defines the absolute measure of dispersion.

It depends on the lower quartile Q1 and the upper quartile Q3. The difference Q3−Q1 is called the inter quartile range. The difference Q3−Q1 divided by 2 is called semi-inter quartile range or the quartile deviation.
Formula
Q.D.=Q3−Q12
Coefficient of Quartile Deviation
A relative measure of dispersion based on the quartile deviation is known as the coefficient of quartile deviation. It is characterized as
Coefficient of Quartile Deviation =Q3−Q1Q3+Q1
