Answer: The median of the given data is 76.36
Step-by-step explanation:
First we will find
Therefore from attached table we have CF= 43 , f = 22 and L= 70
As we know
Hence, the median of the given data is 76.36
Median = 76.36
Step-by-step explanation:
Class interval Frequency Cumulative frequency
0−10 0 0
10−30 10 10
30−50 15 25
50−70 18 43
70−90 22 65
90−110 22 87
110−130 9 96
130−150 4 100
N = 100, N/2 = 50
The cumulative frequency just greater than N/2 = 50, then median class is 70−90 such that,
lower limit =70,
width of the median class(h) = 90−70 =20,
f = 22, cf = 43
Median = L + × h
= 70 + × 20
= 76.36
