Question:
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.
Solution:
The minimum observation is 0 and the maximum observation is 8.
Therefore, classes of the same size covering the given data are 0-2, 2-4, 4-6 and 6-8.
