Question

22,12,14,7,18,16,11,15,12 find quartile deviation​

Answer 1

Answer:

2

Step-by-step explanation:

arranging in ascending order,

7,11,12,12,14,15,16,18,22

here N = 9

Now, Q1 = (9+1)/4 th term = 2.5th term = (12+14)/2=13

Q3 = 3(9+1)/4 th term = 7.5th term = (16+18)/2=17

now, Quartile deviation = (Q3-Q1)/2 = (17-13)/2 =2
