Answer:
No, correct option is (A) 117.5
Step-by-step explanation:
Interquartile range (IQR) measures the skewness using 50% of the data. It is the difference between the third quartile and the first quartile. i.e.
IQR = Q₃ - Q₁
For finding the Interquartile Range of the data:
100, 120, 130, 188, 196, 220, 265, 300
- Divide the data into two parts:
(100, 120, 130, 188) (196, 220, 265, 300)
2. Now finding the medians of both halves of the data that will be our First and Third Quartile of data.
So, Q₁ = 125 and Q₃ = 242.5
Now, using IQR = Q₃ - Q₁
= 242.5 - 125 = 117.5
Hence, Correct option is Option (A).
