Calculate median of the following frequency distribution table C.I 1-4 4 - 7 7 - 10 10 - 13 13 – 16 16 – 19 F 6 30 40 16 4 4​

Answer»

ong>Answer:

firstly we FIND the c.f of this table (c.f:- f1-f2)

C.F:-

6+0=6

6+30=36

36+40=76

76+16=92

92+4=96

96+4=100

then:-

MEDIAN= L+[(n÷2)-Pc.f÷f]c

l=lowest LIMIT of median class

Pc.f=privious commutive frequency

n=total no. of observation

c=size of median class

median=
