What Is Statistics?

Statistics is the science of learning from data, and of measuring, controlling, and communicating uncertainty; and it thereby provides the navigation essential for controlling the course of scientific and societal advances (Davidian, M. and Louis, T. A., 10.1126/science.1218685).

Statisticians apply statistical thinking and methods to a wide variety of scientific, social, and business endeavors in such areas as astronomy, biology, education, economics, engineering, genetics, marketing, medicine, psychology, public health, sports, among many. "The best thing about being a statistician is that you get to play in everyone else's backyard." (John Tukey, Bell Labs, Princeton University). Many economic, social, political, and military decisions cannot be made without statistical techniques, such as the design of experiments to gain federal approval of a newly manufactured drug.

Job Characteristics

• Use data to solve problems in a wide variety of fields

• Apply mathematical and statistical knowledge to social (Education),

• economic, medical, political, and ecological problems

• Work individually and/or as part of an interdisciplinary team

• Travel to consult with other professionals or attend conferences, seminars, and continuing education activities

• Advance the frontiers of statistics, mathematics, and probability through education and research

Statisticians provide crucial guidance in determining what information is reliable and which predictions can be trusted. They often help search for clues to the solution of a scientific mystery and sometimes keep investigators from being misled by false impressions.

What Do Statisticians Do?

The world is becoming quantitative. More and more professions, from the everyday to the exotic, depend on data and numerical reasoning. Data are not just numbers, but numbers that carry information about a specific setting and need to be interpreted in that setting. With the growth in the use of data comes a growing demand for the services of statisticians, who are experts in the following:

• Producing trustworthy data

• Analyzing data to make their meaning clear

• Drawing practical conclusions from data

Examples of Statistics Careers

Education

The role of statistics in education can mean anything from the statistics of how many people go to school or college, to how or why statistics is taught in school. Statistical data on how many people go to school is important to see how educated we are and how many people can afford school. Teaching statistics in school is important because statistics are used in every day life in every field of business. The more education you have in statistical data, the better off you will be in your chosen career.

Medicine

The search for improved medical treatments rests on careful experiments that compare promising new treatments with the current state of the art. Statisticians work with medical teams to design experiments and analyze the complex data they produce.

Environment

Studies of the environment require data on the abundance and location of plants and animals, on the spread of pollution from its sources, and on the possible effects of changes in human activities. The data are often incomplete or uncertain, but statisticians can help uncover their meaning.

Industry

The future of many industries and their employees depends on improvement in the quality of goods and services and the efficiency with which they are produced and delivered. Improvement should be based on data, rather than guesswork. More companies are installing elaborate systems to collect and act on data to better serve their customers.
