Theory:

In our daily life, we have read about information in the form of tables, graphs from books, newspapers, television, etc. The information can be temperatures in cities, number of people living, the weight of the students studying in a school, etc. These facts or information, which are in numerical form, is called data.
Data is a collection of facts or information which is used for a specific purpose.
The word "Data" is in the plural form and is derived from the Latin word "datum".
 
From these obtained data, we extract certain information. This extraction of information leads to a new concept in mathematics called "statistics".
Statistics is the branch of mathematics that deals with the collection, organising, analysing and interpretation of data.
