Question

find out the numbers of family members in your society . calculate the mean , meadiN and mode . draw bar graph​

Answer 1

Answer:

Data of number of family members of 10 neighborhood families:

2, 4, 4, 6, 2, 3, 5, 5, 7, 4

Mean :

( Σ xi )  = 2 + 4 + 4 + 6 + 2 + 3 + 5 + 5 + 7 + 4 = 42

n = 10

mean =  ( Σ xi ) / n.

= 42/10

= 4.2

Median :

2, 2, 3, 4, (4, 4,) 5, 5, 6, 7

Median = 5th observation + 6th observation / 2

= 4 + 4 / 2

= 8 / 2

4

Mode :

The value which appear most  often is 4. it appear more time than any  of the other data values.

Thus, the mode is 4.

Thus, the mean median and mode​ for my 10 neighborhood families are 4.2, 4 and 4 respectively.
