# Number of village

Given is the frequency distribution table for ungrouped data.

We have 20 villages each have 12k population,

15 villages each have 5k population,

And so on…

This also implies that,

Total population of 20 villages = 12 × 20 = 240,

Total population of 15 villages = 5 × 15 = 75,

And so on…

Mean of such ungrouped data is given by   [ ∑xifi = 2571 & ∑fi = 145]

Mean = 17.731

Mean = 17.731 × 1000

Mean = 17731

Thus, average population in each village is 17731.
