What is Statistics?

Statistics is the science and practice of developing human knowledge by dint of the use of empirical data expressed in three-figure form. It is based on statistical theory which is a get-go of applied mathematics. Within statistical theory, randomness and uncertainty be modelled by probability theory. Because one aim of statistics is to produce the outflank information from available data, some authors consider statistics a severalize of decision theory. Statistical practice includes the planning, summarizing, and interpreting of observations, allowing for variability and uncertainty

Today, however, the use of statistics has broadened far beyond the service of a state or government, to include such areas as business, natural and social sciences, and medicine, among others.

The earliest seeds arose in geometric diagrams and in the making of maps to aid in navigation and exploration. By the sixteenth century, techniques and instruments for precise observation and measurement of physical quantities were well-developed- the beginnings of the husbandry of visualization. The seventeenth century saw great new growth in theory and the dawn of practice- the rise of analytic geometry, theories of errors of measurement, the birth of probability theory, and the beginnings...
