### The Statistics Profession

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 answer questions about the present and future.
• Knowledge helps plan future tests, determines resource allocation, and improves quality.
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.
• Manufacturing
• Build products and deliver services that satisfy consumers and increase the corporation’s profit margin
• Marketing
• Design experiments for new products, conduct focus groups and sample surveys, and perform field experiments in test markets to determine product viability
• Engineering
• Make a consistent product, detect problems, minimize waste, and predict product life in electronics, chemicals, aerospace, pollution control, construction, and other industries
• 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
Health and Medicine
• 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
• Public Health
• Prevent disease, prolong life, and promote health through organized community efforts, including sanitation, hygiene education, diagnoses, and preventative treatment
Health and Medicine
• 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
• Genetics
• Label possible indicators of genetic abnormalities, such as birth defects and early aging, or breed desirable characteristics in plant offspring
Learning
• Education
• Teach K-12 through post-graduate students, assess teacher effectiveness, or develop statistical models to represent student learning
Learning
• Science Writing & Journalism
• Work with mass media, universities, and corporations to produce news briefs, articles, news releases, and other reports
Research
• Government
• Work in regulations for stock trading, pollution, and drug approvals, or testify in court proceedings, congressional hearings, and lobbying arguments
Research
• Survey Methods
• Collect data in the social sciences, education, law, forestry, agriculture, biology, medicine, business, and e-commerce, and for the government
Social Statistics
• Law
• Analyze data in court cases, including DNA evidence, salary discrepancies, discrimination law suits, and disease clusters
Social Statistics
• Consulting
• Work on a temporary basis on a variety of projects including quality improvement, pharmaceuticals, ecology, and engineering
Natural Resources
• Agriculture
• Study chemical pesticides, hydrogeology, veterinary sciences, genetics, and crop management in order to ensure optimal yield
Natural Resources
• Ecology
• Address questions about the earth’s natural environment, including animal populations, agricultural protections, and fertilizer and pesticide safety
