Question

The following data gives the number of children in 40 families:
1, 2, 6, 5, 1, 5, 1, 3, 2, 6, 2, 3, 4, 2, 0, 4, 4, 3, 2, 2, 0, 0, 1, 2, 2, 4, 3, 2, 1, 0, 5, 1, 2, 4, 3, 4, 1, 6, 2, 2.
Represent it in the form of a frequency distribution.

Answer 1

Arranging the dates in ascending order, we get:

0, 0 ,0 , 0, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2,2,2, 3, 3, 3, 3, 3, 4, 4, 4, 4, 4, 4, 5, 5, 5, 6, 6, 6

There are:
4 families with no children
7 families with 1 child
12 families with 2 children
5 families with 3 children
6 families with 4 children
3 families with 5 children
3 families with 6 children

The frequency distribution table for the above data can be generated as below:

Number of children	Tally mark	Number of families (frequency)
0	$\left|\right|\left|\right|$	4
1	$\cancel{\left|\right|\left|\right|}\left|\right|$	7
2	$\cancel{\left|\right|\left|\right|}\cancel{\left|\right|\left|\right|}\left|\right|$	12
3	$\cancel{\left|\right|\left|\right|}$	5
4	$\cancel{\left|\right|\left|\right|}$ $|$	6
5	$\left|\right||$	3
6	$\left|\right||$	3
	Total	40
