Question

find the median where no of letters are 0-5,5-10​

Answer 1

Answer:

2.5 is the answer

Answer 2

Answer:

X

Frequencies(f)

Cumulative frequency (cf)

0−5

4

4

5−10

8

4+8=12

10−15

12

12+12=24

15−20

16

24+16=40

20−25

20

40+20=60

n=Σf=60

n=Σf= Total number of frequency =60

So, the median class is 15−20

L= Lower limit of the median class =15

cf= Cumulative frequency of the class preceding the median class =24

f= Frequency of the median class =16

h= class width=5

Hence, the median is 16.875
