# Number of familie

Given is the frequency distribution table for ungrouped data.

We have

11 families each have no children,

25 families each have 1 child,

And so on…

This also implies that,

Total number of children of 11 families = 0 × 11 = 0,

Total number of children of 25 families = 1 × 25 = 25,

And so on…

Mean of such ungrouped data is given by

[ ∑xifi = 144 & ∑fi = 84]

Mean = 1.7143

Thus, mean number of children per family is 1.7143.
