3. The Statistics Profession

4. 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.’ What Is Statistics?

Set-up formal hypotheses in terms of variables and parameters Do a study to gather sample data (survey, historical, observational, designed expt.) Analyze sample data using statistical methods Results consistent with the hypothesis? NO YES Dr. or Prof. Thesis!? Dissertation! Tenure, Promotion, Recognition Wealth??! STATISTICS

7. Scope and Variety of Statistics

8. Environment Agriculture, Ecology, Forestry, Animal Populations Government Census, Law, National Defense Physical Sciences Astronomy, Chemistry, Physics Areas where STATISTICS are used Health & Medicine Genetics, Clinical Trials, Epidemiology, Pharmacology Business Economics, Engineering, Marketing, Computer Science

9. 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. Why Study Statistics?

10. 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. What Do Statisticians Do?

11. Manufacturing –Build products and deliver services that satisfy consumers and increase the corporation’s profit margin Business and Industry

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

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

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 Business and Industry

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

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

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

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

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

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

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

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

23. Law –Analyze data in court cases, including DNA evidence, salary discrepancies, discrimination law suits, and disease clusters Social Statistics

24. Consulting –Work on a temporary basis on a variety of projects including quality improvement, pharmaceuticals, ecology, and engineering Social Statistics

25. Agriculture –Study chemical pesticides, hydrogeology, veterinary sciences, genetics, and crop management in order to ensure optimal yield Natural Resources

26. Ecology –Address questions about the earth’s natural environment, including animal populations, agricultural protections, and fertilizer and pesticide safety Natural Resources
