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

In the question, the data of the number of children in 40 familiare is given as: 

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. 

On arranging the children 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 

Now, we plot this data in a frequency distribution table as given below:
