The Statistics Profession
4
What Is Statistics?
• American Heritage Dictionary The mathematics
of the collection, organization, and
interpretation of numerical data, especially the
analysis of population characteristics by
inference from sampling.
• Statisticians collect and analyze data, then
calculate results using a specific design. They
draw conclusions and make decisions in the face
of uncertainty and by exploiting order out of
chaos.

Why Study Statistics?
• Collecting data on subsets of the population
(samples) can give valid information about the
whole population.
• Knowing what has happened in the past can help
• Knowledge helps plan future tests, determines
resource allocation, and improves quality.

10
What Do Statisticians Do?
• Study the safety of nuclear power plants
• Evaluate the environmental impact of pollution
• Determine the effectiveness of new drugs
• Estimate the U.S. unemployment rate
• Analyze consumer demand for products
• Plan and analyze agricultural experiments
• Do mathematical research.

11
• Manufacturing
• Build products and deliver services that satisfy
consumers and increase the corporations profit
margin

12
• Marketing
• Design experiments for new products, conduct
focus groups and sample surveys, and perform
field experiments in test markets to determine
product viability

13
• Engineering
• Make a consistent product, detect problems,
minimize waste, and predict product life in
electronics, chemicals, aerospace, pollution
control, construction, and other industries

14
• Statistical Computing
• Work in software design and development, testing,
quality assurance, technical support, education,
marketing, and sales to develop code that is both
user-friendly and sufficiently complex

15
• Epidemiology
• Work on calculating cancer incidence rates,
monitor disease outbreaks, and monitor changes in
health-related behaviors such as smoking and
physical activity

16
• Public Health
• Prevent disease, prolong life, and promote health
through organized community efforts, including
sanitation, hygiene education, diagnoses, and
preventative treatment

17
• Pharmacology
• Work in drug discovery, development, approval,
and marketing, to ensure the validity and
accuracy of findings at all stages of the process

18
• Genetics
• Label possible indicators of genetic
abnormalities, such as birth defects and early
aging, or breed desirable characteristics in
plant offspring

19
• Education
• Teach K-12 through post-graduate students, assess
teacher effectiveness, or develop statistical
models to represent student learning

20
• Science Writing Journalism
• Work with mass media, universities, and
corporations to produce news briefs, articles,
news releases, and other reports

21
• Government
• Work in regulations for stock trading, pollution,
and drug approvals, or testify in court
proceedings, congressional hearings, and lobbying
arguments

22
• Survey Methods
• Collect data in the social sciences, education,
law, forestry, agriculture, biology, medicine,
business, and e-commerce, and for the government

23
• Law
• Analyze data in court cases, including DNA
evidence, salary discrepancies, discrimination
law suits, and disease clusters

24
• Consulting
• Work on a temporary basis on a variety of
projects including quality improvement,
pharmaceuticals, ecology, and engineering

25
• Agriculture
• Study chemical pesticides, hydrogeology,
veterinary sciences, genetics, and crop
management in order to ensure optimal yield

26
• Ecology
environment, including animal populations,
agricultural protections, and fertilizer and
pesticide safety
