QUESTION :

For the series with observation 10, 12, 15, 8, 24, 28, 16, 42, 56, 32 and 18 then quartile deviation is _______.

ANSWER :

EXPLANATION :

Quartile deviation divides the series into four equal parts and measures the distance average between the third and the first quartile. The first quartile is denoted as Q1 and the third quartile is denoted as Q3 .

In the given series,

SERIES : 10,15,17,18,20,22,25,28,29,32,34

Q1= 17 and Q3=29

Therefore, Quartile deviation = (Q3-Q1) /2

= (29-17)/2

= 12/2

= 6

FINAL ANSWER : 6
