 Description  
 Statistics:  The branch of mathematics that deals with the collection, organization, and interpretation of data.

The first part of the word statistics comes from the German word for state (staat). The word was used as a term to describe the practice of the state collecting information on births and deaths more than 300 years ago.

We see statistics in almost every medium: newspapers, radio, television, and the Internet. It is important for us as the audience of these media to have some knowledge of the rules and methods used in the statistics that give us the results we see or hear.

Many activities and interests today depend on statistics. Some of these are:

  • Medicine
  • Environment
  • Industry
  • Government surveys
  • Marketing research
  • Advertising
  • Sports
  • Economics
  • Stock market
  • Education
  • Consumer reports

Examples of Statistics: Unemployment rate, consumer price index, rate of violent crimes, infant mortality rates, poverty rate of a country, batting average of a baseball player, on base percentages of a baseball player, salary rates, standardized test results.
