Statistics has been derived from the Latin word status, an Italian word, statist, or a German word, statistic, all of which mean a ‘political state’. The use of statistics has been employed in various fields like biostatics, agriculture, economics, sociology, business management, etc.

The field of statistics is not new, and its beginning can be dated back to the times of the beginning of human activities. However, the utilization of statistics has increased over the years. In earlier times statistics was referred to as the science of statecraft and were used for collecting data related to population count in a ruler’s area – crime, mortality, income, birth rate – and were also used for keeping a track of the key events of the time for administrative purposes. However, in modern times, the use of statistics has been employed in a variety of fields. Its use has been extended in the areas of formulation and prediction of future plans and policies of the state administration.

The word statistics is used in multiple numbers of ways. There are some instances where it is used in plural form that reflects upon the word statistics, being referred to as numerical data and statements. There are other instances where it is used in singular form to refer to the subject of study just like any other subject, like mathematics, economics, etc.

The importance of statistics has subsequently increased over all these passing years. It is because of the benefits that it provides to the user. The statistical findings have made assumption of anomalous information easy. In fact, the use of the statistical thinking has become necessary for citizens.
