Question

Calculate the mean, median of the number of persons per house in a village with the help of the following information:
number of person per house 1 2 3 4 5 6 7 8 9 10
number of house 26 113 120 95 60 42 21 14 5 4
​

Answer 1

Given:

number of person per house 1 2 3 4 5 6 7 8 9 10

number of house 26 113 120 95 60 42 21 14 5 4

Calculate mean of the number

1+2+3+4+5+6+7+8+9+10=55

55/10=5.5

calculate median of the number

median=size of(N+1/2)th item

M=10+2/2

  =6

M= size of 6th item

  =42

Answer 2

Given:

number of person per house 1 2 3 4 5 6 7 8 9 10

number of house 26 113 120 95 60 42 21 14 5 4

Find:

Calculate the mean, median of the number of persons per house

Let,

$1+2+3+4+5+6+7+8+9+10=55$

$\frac{55}{10} =5.5$

Lets calculate median of the number

median = size of(N+1/2)th item

$M=10+2/2$

$=6$

M = size of 6th item

= 42
