Quartile Deviation, also known as the Semi-Interquartile Range, is a measure of dispersion in statistics that indicates the spread of the middle 50% of a data set. It is less affected by extreme values compared to the range, making it a more robust measure of variability. The quartile deviation is calculated using the first quartile (Q1) and the third quartile (Q3), which divide the data into four equal parts. Q1
