Question

Find the median, lower quartile and upper quartile for the data. 9, 5, 7, 11, 13, 17, 15

Answer 1

Step-by-step explanation:

The median is : 9

1,3,5,7,9,11,13,15,17

Median =9

So, the lower half from the median = first quartile =1,3,5,7

Median of the first quartile =

2

3+5

=4

Similarly, the upper half from the median = third quartile =11,13,15,17

Median of the third quartile =

2

13+15

=14

IQR = third quartile − first quartile

=14−4=10.
