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, taking classes 0-2, 1-4, etc.

Minimum observation = 0


Maximum observation = 6


The classes of equal size covering the given data are:


0-2, 2-4, 4-6, 6-8


So, frequency distribution table will be as given below,


Class



Frequency



0 – 2



11



2 – 4



17



4 – 6



9



6 – 8
