Following data gives the number of children in $40$ families:
$2, 1, 5, 6, 1, 5, 1, 3, 2, 6, 2, 3, 4, 2, 0, 4, 4, 3, 2, 2, 0, 0, 1, 2, 2, 4, 3, 2, 1, 0, 5, 1, 2, 4, 3, 4, 1, 2, 2, 6 .$
Represent it in the form of a frequency distribution, taking classes $0 - 2, 0 - 4$ ; etc.

Solution

Step 1: Organize the data in tabular form:
Class interval
Frequency
$0 - 2$
$11$
$2 - 4$
$17$
$4 - 6$
$9$
$6 - 8$
$3$
Total
$40$
Hence, the frequency distribution table is formed with the class intervals $0 - 2, 2 - 4, 4 - 6 a n d 6 - 8$ each having frequency of $11, 17, 9 a n d 3 .$ respectively.
