- Statistics is the scientific application of mathematical principles to the collection, analysis, and presentation of numerical data.
- Statisticians apply their mathematical and statistical knowledge to the design of surveys and experiments; the collection, processing, and analysis of data; and the interpretation of experiments and survey results.
- Opinion polls, statements about the accuracy of scales and other measuring devices, and information about average earnings in an occupation are all usually the work of statisticians.
- Statisticians may apply their knowledge of statistical methods to a variety of subject areas, such as biology, economics, engineering, medicine, public health, psychology, marketing, education, and sports.
- 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. Statistics might be needed to show whether the seemingly good results of a drug were likely because of the drug rather than just the effect of random variation in patient outcomes.
- One technique that is especially useful to statisticians is sampling—obtaining information about a population of people or of a group of things by surveying a small portion of the total. For example, to determine the size of the audience for particular programs, television-rating services survey only a few thousand families, rather than all viewers.
- Statisticians decide where and how to gather the data, determine the type and size of the sample group, and develop the survey questionnaire or reporting form. They also prepare instructions for workers who will collect and tabulate the data. Finally, statisticians analyze, interpret, and summarize the data with the use of computer software.
- In business and industry, statisticians play an important role in quality control and in product development and improvement. In an automobile company, for example, statisticians might design experiments in which engines are run until failure and breakdown in order to determine the failure time of engines exposed to extreme weather conditions.
- Working for a pharmaceutical company, statisticians might develop and evaluate the results of clinical trials to determine the safety and effectiveness of new medications.
- At a computer software firm, statisticians might help construct new statistical software packages to analyze data more accurately and efficiently.
- In addition to designing experiments for product development and testing, some statisticians are involved in deciding what products to manufacture, how much to charge for them, and to whom the products should be marketed.
- Statisticians also may manage assets and liabilities, determining the risks and returns of certain investments.
- Nearly every government agency employs statisticians. Some government statisticians develop surveys that measure population growth, consumer prices, or unemployment. Other statisticians work for scientific, environmental, and agricultural agencies and may help figure out the average level of pesticides in drinking water, the number of endangered species living in a particular area, or the number of people afflicted with a certain disease.
- Statisticians also are employed in national defense agencies, determining the accuracy of new weapons and the likely effectiveness of defense strategies.
- Because statistical specialists are employed in so many different kinds of work, specialists who use statistics often have different professional designations. For example, a person using statistical methods to analyze economic data may be called an econometrician, while statisticians in public health and medicine may hold titles such as biostatistician or biometrician.
- The demand for individuals with a background is statistics is projected to grow, although some jobs will be in occupations with titles other than statistician.
- The use of statistics is widespread and growing. Statistical models aid in decision making in both private industry and government. There will always be a demand for the skills statisticians provide.
- Technological advances are expected to spur demand for statisticians. Ever-faster computer processing allows statisticians to analyze greater amounts of data much more quickly and to gather and sort through large amounts of data that would not have been analyzed in the past.
- As data processing continues to become more efficient and less expensive, an increasing number of employers will want to employ statisticians to take advantage of the new information available.
- Biostatisticians should experience employment growth, primarily because of the growing pharmaceuticals business. As pharmaceutical companies develop new treatments and medical technologies, biostatisticians will be needed to do research and clinical trials.
- Individuals with a degree in statistics have opportunities in a variety of fields. For example, many jobs involve the analysis and interpretation of data from economics, biological science, psychology, computer software engineering, education, and other disciplines.
- Additional job openings will become available as currently employed statisticians transfer to other occupations, retire, or leave the workforce for other reasons.
- Among graduates with a master's degree in statistics, those with a strong background in an allied field, such as finance, biology, engineering, or computer science, should have the best prospects of finding jobs related to their field of study.
Among the people who work with statistics are those in such diverse occupations as Actuaries, Computer Scientists, Computer software engineers and computer programmers, Computer System Analyst, Economists, Engineers, Financial analysts, Market and survey researchers, Mathematicians, Operation research analysts, Personal financial advisors, and Social Scientists. Some statisticians also work as teachers.
