Answer 2

Given:  a survey was conducted in 25 families of a locality

the number of children in these families

2,2,3,1,1,1,2,2,2,1,1,1,1,2,2,3,1,2,2,1,2,2

To Find: Prepare a frequency distribution of the data.

Solution:

Data given for 22 families, Assuming other 3 families as no children

Number of children   Tally Mark     Frequency

0                                   |||                         3
