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 | 3 |
