Detailed explanation-1: -The interquartile range is the difference between upper and lower quartiles. The semi-interquartile range is half the interquartile range.
Detailed explanation-2: -The lowest quartile (Q1) covers the smallest quarter of values in your dataset. The upper quartile (Q4) comprises the highest quarter of values. The interquartile range is the middle half of the data that lies between the upper and lower quartiles.
Detailed explanation-3: -While the range gives you the spread of the whole data set, the interquartile range gives you the spread of the middle half of a data set.
Detailed explanation-4: -To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
