(ii) Find first second and third quartile of the following data
12, 18, 13,19,16,14,15,17,20.
Ans:
This is ungrouped data. First arrange the data in ascending order.
12,13,14,15,16,17,18,19,20
Now, find median or second quartile. 16
Median position: (n+1) /2 = (9+1)/2=10/2=5th position Counting median= 16
First quartile (Q1) First Quartile Position: (n+1)/4 =10/4=2.5th position So average of 2nd and 3rd positions values= (13+14)/2=13.5
Third quartile (Q3) Third Quartile Position: 3(n+1)/4 =30/4=7.5th position So average of 7th and 8th position values= (18+19)/2=18.5.
