- Half of the difference between the upper and lower quartiles is the Quartile Deviation, which may be calculated numerically.
- Quartile Deviation is also known as the Semi Interquartile range.
- QD denotes quartile deviation, with Q3 denoting the upper quartile and Q1 denoting the lower quartile.
Quartile Deviation Formula
QD = (Q3 – Q1)/2
Important Points

Dispersion can be compared for two or more sets of data using the coefficient of quartile deviation (also known as the quartile coefficient of dispersion).
Formula :
If one set of data has a higher coefficient of quartile deviation than another, the interquartile dispersion of that data set is higher.
