Question

3. Construct the cumulative frequency, distribution of the following distribution and hence find the median group Class Frequency​

Answer 1

Answer:

cf

2

24

33

47

60

Step-by-step explanation:

n/2 = 60/2 = 30

l = 22

h = 4

f = 9

cf = 22

median = l + (n/2-cf)/f × h

= 22 + ( 30-22)/9×4

= 22 + 8/9×4

= 22+ 24/9

= 22+2.67

= 24.67
