Question

χ χ χ 2x
the median of the observations
3'2'4' 9
and x is5 where(x>0) then find the value of x
Find the mode from a frequency distribution.​

Answer 1

Step-by-step explanation:

 x

 10

 11

 12

 13

 14

 15

 f

 1

 4

 7

 5

 9

 8

for a frequency distribution,

So, total number of observation =(1+4+7+5+9+8)=34

It is a even number.

So, median is the value of average of values at (2n)th and (2n+2)th.

∴  Here, median is the average of the values at (234)th or 17th position and (234+2)th or 18th position.
