History of data analysis

This field got its start with capturing and counting census and other demographic data. Later, people figured out that there are better ways of the presentation of information and started tabulating the data.

Then using probabilities, early statisticians estimated the population of cities to plan for the future.

As mathematics advanced, various theories of distribution were formed. One of the most well-known -- and popular still -- theorems is the Bayes law.

Later, statistics as a field really took off. Various sampling methods, least squares methods and hypothesis testing followed soon.
