Given:
<span>11 11.5 10.5 17 14.5 14.5 18 17 19

Arrange in chronological order from least to greatest.
10.5 ; 11 ; 11.5 ; 14.5 ; 14.5 ; 17 ; 17 ; 18 ; 19

</span><span>I used an online lower and upper fence calculator to get the necessary data.

Minimum: 10.5
Maximum: 19
Q1: 11.25
Q2 or median: 14.5
Q3: 17.5

Interquartile range can be solved by subtracting the value of Q1 from the value of Q3

IQR = Q3 - Q1
IQR = 17.5 - 11.25
IQR =  6.25  CHOICE A. </span>
