Answer 2

The interquartile range of the following body weights(in Kg) of children is (a) 7, 16

The Interquartile Range(IQR)

The interquartile range (IQR) is determine, ​first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

Here to find the (IQR) we have to arrange the data in increasing order.

7 , 7 , 8.5 , 11 , 11 , 12 , 12 , 13.5 , 16

The middle term of this data is being bold in series.

The values are quartile 1 (Q1) = $\frac{7+ 8.5}{2}$  = 7.75

The values are quartile 3 (Q3) = $\frac{12+13.5}{2}$ = 12.75

Since the value of (Q1) and (Q3) are 7.75 and 12.5 respectively.

Which fall in the range of option (a)  7 , 16
