|
|
IQR = 150-119 = 31
|
|
|
IQR = 150-125 = 25.
|
|
|
IQR = 150-125 = 75.
|
|
|
IQR = 150-119 = 31.

Explanation:
Detailed explanation-1: -The formula for finding the interquartile range takes the third quartile value and subtracts the first quartile value. Equivalently, the interquartile range is the region between the 75th and 25th percentile (75 – 25 = 50% of the data).
Detailed explanation-2: -The interquartile range is the difference between the first quartile 7 and the third quartile 15 . In this case, the difference between the first quartile 7 and the third quartile 15 is 15−(7) .
