A data set is made up of these values. 1,4,5, 6, 6,9,11 Find the interquartile range.
A. 4 1=3
B. 11-9 = 2
C. 11 1= 10
D. 9-4 = 5​

Answer 1

Answer:

Option D

9 – 4 = 5

Step-by-step explanation:

Given;

1, 4, 5, 6, 6, 9, 11

Now,

Q1.) The median of the lower half is 4

Q3.) The median of the upper half is 9

So,

IQR is the difference of the above two numbers:

IQR = Q3 – Q1 = 9 – 4 = 5

Thus, The answer is 5
