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

Text Solution

Verified by Experts

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 marks in bunches of five, the fifth one crossing the other diagonally, i.e., `cancel(IIII)`.
Hence, we may prepare a frequency table as shown below.
