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.

Physical Sciences Astronomy, Chemistry, Physics
Areas where STATISTICS are used
Health Medicine Genetics, Clinical
Trials, Epidemiology, Pharmacology
Environment Agriculture, Ecology,
Forestry, Animal Populations
Government Census, Law, National Defense
9
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
    answer questions about the present and future.
  • 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
  • Address questions about the earths natural
    environment, including animal populations,
    agricultural protections, and fertilizer and
    pesticide safety
