    • 6. Data Flood Data-Based Decisions Customer Perspective
    • 7. Learning About Customer Problems and Data
    • 8. Statistical Needs in Corporate Environments: The Five D’s 1. Data planning  Design of surveys, experiments, clinical trials, … 2. Data access and management  Disparate data sources and poor data quality undermine analysis  Databases, data warehouses (controlled by IT, not analysts) 3. Data preparation  Getting the data into analysis-ready form (“80% of the effort”) 4. Data analysis and modeling 5. Delivery of analytical results  User interfaces, graphics, web reports, FDA submissions, …
    • 9. What’s Involved in Producing Statistical Software? 1. Listening to customers 2. Keeping up with advances in statistical methodology 3. Designing, writing, testing code 4. Writing user documentation 5. Providing technical support and training 6. Consulting with customers 7. Presenting to customers Statistical software testers Cheryl LeSaint and Yu Liang
    • 10. Growth Opportunities for Statisticians 1. Development of analytical solutions  Integrated solutions for business problems  Developed by interdisciplinary teams  industry experience  software development skills  expertise in statistics, data mining, operations research  Examples  fraud detection for banks  credit scoring  customer retention and marketing automation  credit, market, and operational risk analysis  web analytics  warranty analysis
    • 11. Growth Opportunities for Statisticians (cont’d) 2. Consulting in financial and retail industries  Ability to formulate a business problem with a statistical model  Examples  survival models for customer lifetime value  predictive model for repayment behavior  forecasting demand for store items  experimental design for direct marketing
    • 12. Early Success Factors: Undergraduate Preparation  How much math do I need for graduate work in statistics?  calculus, linear algebra  statistics is not a branch of mathematics, but you need to be mathematically prepared  What should I major in?  math, statistics, biology, computer science, physics, engineering, economics, psychology, …  What else should I take?  probability and statistics--enough to understand how modern statistics is used to analyze data and solve problems  computer programming  technical writing
    • 13. Early Success Factors: Undergraduate Preparation Explore statistical careers through internships, StatFests, and summer opportunities North Carolina State Summer Institute for Biostatistics Training Field trip to SAS
    • 14. Early Career Success Factors: Graduate Training  Apply to the right program in statistics or biostatistics  Where would you like to work when you finish?  Are you interested in academic research and teaching?  Are you interested in business or government?  Talk to faculty and alumni—they’ll be glad to advise you!  Consider an in-demand area of statistics  Survey design and analysis  Econometric modeling  Statistical computing  Become a student membership of ASA!  Internship opportunities in December Amstat News
    • 15. Early Career Success Factors Interviewing  Research the organization in advance  Ask perceptive questions  Are the staff absorbed in their work?  What brings them back to work year after year?  What is the least satisfying aspect of their work?  What is the most rewarding aspect of their work?  If you are excited about what they are doing, they will be excited about you!
    • 16. Early Career Success Factors: Where to Start Your Career  Excellence attracts excellence, so look for  group of flourishing statisticians  statisticians valued as problem formulators/solvers  statisticians collaborating with others  senior statisticians serving as mentors and leaders  statisticians active professionally (members of ASA)  Traps to avoid  isolation from other statisticians  limited understanding of what statisticians do (“just run the reports”)  lack of support for professional activity
    • 17. Early Career Success Factors: Becoming a Prized Professional  Work on your writing skills  Careful motivation  Clear conclusions  Learn to give presentations that anticipate and meet audience needs  Develop special computing skills  Management of large data sets  Advanced statistical programming  Become active in the ASA  Keep learning  Give back to the profession!
