Given below is the data showing the number of children in a family, in a locality of 15 families.
1,3,5,4,3,2,1,1,3,2,2,1,4,2 and 1. and Draw the frequency table to represent the data.

Explanation

Arranging the data in ascending order we have : 1,1,1,1,1,2,2,2,2,3,3,3,4,4,5. To count, we can use tally marks. We record tally mark in bunches of five, the one crossing the other diagonally, i.e., `cancel(III)`. Thus, we may prepare a frequency table as shown below :
`{:("Number of Children","Tally Marks","Number of Families (Frequency)",),(1,cancel(IIII),5,),(2,IIII,4,),(3,III,3,),(4,II,2,),(5,I,1,):}`
