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, 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.

Answer 1

Here, the maximum and minimum values of the variate are 6 and 0 respectively.

So the range = 6 – 0 = 6

Here, we will take class size 1. So we must have 6 classes each of size 1.

Therefore, the frequency distribution in which the lower limit is included and upper limit excluded is:
