Given : Class interval & Frequencies
To find : Median of the Data
Solution:
10.5 - 15.5 3 3
15.5 - 20.5 5 8
20.5 - 25.5 9 17
25.5 - 30.5 12 29
30.5 - 35.5 7 36
55.5 - 40.5 4 40
40/2 = 20
Hence lies in 25.5 - 30.5
Median = 25.5 + 5 * ( 40/2 - 17)/12
= 25.5 + 5 * 3 /12
= 25.5 + 1.25
= 26.75
26.75 is the median of the Data
-4 ,6 Divides A (-6 , 10) & ( 3 , -8) into 1 : k ratio
=> - 4 = (3 - 6k)/(k + 1) or 6 = ( -8 + 10k)/(k + 1)
=> -4k - 4 = 3 - 6k or 6k + 6 = -8 + 10k
=> 2k = 7 or 14 = 4k
=> k = 7/2 or 7/2 = k
1 : k
= 1 : 7/2
= 2 : 7
