STATISTICS: Statistics is the area of study dealing with the presentation, analysis and interpretation of data.

The word ‘statistics’ appears to have been derived from the Latin word ‘status’ meaning ‘a (political) state’. In its origin, statistics was simply the collection of data on different aspects of the life of people, useful to the State. Over the period of time, however, its scope broadened and statistics began to concern itself not only with the collection and presentation of data but also with the interpretation and drawing ofinferences from the data. Statistics deals with collection, organization, analysis and interpretation of data. The word ‘statistics’ has different meanings in different contexts.
