Section A
Question 1:

(i) Arrange the following set of data in ascending order and write down the frequency table showing the frequency of each term in front of it
Solution:

1,1,1,2,2,2,2,3,3,3,3,3,3,5,5,5,5,5,6,7,7,7,8,8,8,8,9,9,9,10

(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.

Say thanks to me

Plz sister send me section c Solved Answer plzzz

hard copy pr hy, rat ko upload kr dun gi

tions
