Answer:
The IQR of the data set is 4.5
Step-by-step explanation:
Given:
10 13 15 12 12 4 12 17
12 13 15 18 10 11 20 19
Now, to determine the IQR (interquartile range) of this data set.
So, <em>we need to set the data in numerical orders:</em>
4 10 10 11 12 12 12 12
13 13 15 15 17 18 19 20
Now,<em> we split this in half and get the medians of both half:</em>
<u>4 10 10 11 12 12 12 12 </u> Median 1 = 11.5
<u>13 13 15 15 17 18 19 20 </u> Median 2 = 16
Getting the medians of both half now we subtract the median 1 from median 2:
IQR = 16 - 11.5
IQR = 4.5.
Therefore, the IQR of the data set is 4.5
