  1. This is how we do it: teaching SAS in the Cal Poly Statistics Department Rebecca Ottesen, Jimmy Doi, Ulric Lund, Karen McGaughey Presented by Jimmy Doi (jdoi@calpoly.edu) Department of Statistics California Polytechnic State University, San Luis Obispo

  2. Outline • Two Major Components • Teaching SAS at Cal Poly • 3 Types of Classes using SAS • Cal Poly Resources • SAS Resources • Knowledge Base • Support • Training/Bookstore • Community

  3. Background • Cal Poly Statistics Department • College of Science and Mathematics • Formerly Computer Science and Statistics Department (1970-84) • Department of Statistics (1984-Present) • Offer Statistics Major and Minor • 2011: 15 tenure track faculty (note) • 2011: 10 lecturers • Strong reputation as a leader of Statistics Education • Very rigorous curriculum (semi-masters) • One of the top undergrad statistics programs

  4. Background • Rebecca Ottesen • Faculty since 1998 • Ulric Lund • Faculty since 2001 • Jimmy Doi • Faculty since 2003 • Karen McGaughey • Faculty since 2003 • Many combined years using SAS for • course instruction • conducting research • consulting projects • other occupations

  5. Importance of SAS for Students • Crucial component of our students’ training • Required course for all statistics majors • Commonly taken by statistics minors (esp. Bus.) • Many job opportunities (even at entry-level) • new hires able to contribute to projects right away • “Hit the ground running” • Graduate School • join research projects requiring data management, programming, and analysis • instantly incorporate software into classes

  6. The Cal Poly Model: Courses • SAS Programming • DATA step programming, inputting real data, working with SAS/BASE PROCs • Statistical Methods and Theory • Using SAS for pedagogical support • Real-World Application and Academic Research • Hands-on experience with real (and often messy) data sets

  7. The Cal Poly Model: Courses • SAS Programming • STAT 330 (Statistical Computing using SAS) • Data step programming, macros and basic PROCS • Since 1980s • Required course of all stat majors • Offered twice a year (very popular) • STAT 440 (Prep’n for the SAS Certification Exam) • Expansion of topics from STAT 330, focus on Base Certification Exam • Since 2005 (created by R. Ottesen) • Offered every spring (very successful)

  8. Books: SAS Programming and Certification Course

  9. The Cal Poly Model: Courses • Statistical Methods and Theory • STAT 418 (Categorical Data Analysis) • Contingency tables, logistic & log-linear models • Main PROCs: FREQ, GENMOD, LOGISTIC • STAT 423 (Advanced Design of Experiments) • Split-plots, repeated measures, analysis of covariance • PROC MIXED • Other courses: Applied Regression Analysis, Multivariate Analysis, Survival Analysis, Time Series, Survey Sampling

  10. The Cal Poly Model: Courses • Real-World Application and Academic Research • STAT 465 (Statistical Communication and Consulting) • Use SAS to analyze real and mock statistical consulting projects • Senior Project (required of all Cal Poly students) • Faculty supervised projects (independent research projects) • Many senior projects require computational investigations where SAS has been used

  11. The Cal Poly Model: Audience • Bachelor of Science Statistics Major • Statistics Minor • Classes have a mixture of majors and minors • Classes have a mixture of programming skills • Effective Tactic: Assigning “Mentoring Pairs” • Survey all students on their programming skills • Create teams of two: 1 novice with 1 skilled • During team projects ensure novice spends more time at keyboard

  12. Statistics Studio Classroom Instructor’s Terminal • Images from any machine can be displayed on all (or just side monitors) • After assigning tasks instructor can circulate room to check on progress • Mentoring Pairs – Identify novice/skilled Instructor 12 Side Monitors Printer 1 Printer 2 24 Student Terminals

  13. Statistics Studio Classroom Instructor’s Terminal • Images from any machine can be displayed on all (or just side monitors) • After assigning tasks instructor can circulate room to check on progress • Mentoring Pairs – Identify novice/skilled • = skilled Instructor 12 Side Monitors Printer 1 Printer 2 24 Student Terminals

  14. Statistics Studio Classroom Instructor’s Terminal • Images from any machine can be displayed on all (or just side monitors) • After assigning tasks instructor can circulate room to check on progress • Mentoring Pairs – Identify novice/skilled • = skilled • Move students: 2 novice/skilled per table Instructor 12 Side Monitors Printer 1 Printer 2 24 Student Terminals

  15. Statistics Studio Classroom Instructor’s Terminal • Images from any machine can be displayed on all (or just side monitors) • After assigning tasks instructor can circulate room to check on progress • Mentoring Pairs – Identify novice/skilled • = skilled • Move students: 2 novice/skilled per table Instructor 12 Side Monitors Printer 1 Printer 2 24 Student Terminals

  16.

  17. Lecture: SAS Programming Class Delivery Methods: • Powerpoint Presentations with Programming Examples • Fill-in Course Notes with Programming Examples • Short Discussion with In-Class Activities • GOAL – Strong emphasis on developing good programming skills: well-structured, efficient, and well-commented code

  18. Lecture: Stat Methods Class using SAS • Course notes with embedded SAS template codes and output • Only minor adjustments required for students to apply SAS template code to HW and projects • Provide complete interpretation of corresponding SAS output • Stat methods courses goal:Less emphasis on SAS programming nuances, greater emphasis on SAS output and interpretations

  19. Obtaining the SAS Software • Academic Site License • Cal Poly site license allows students needing SAS for educational purposes to obtain/install SAS • SAS OnDemand for Academics (Fall 2011) • Free program for academic teaching/research • Allows access to specific components of SAS • Included products: Enterprise Guide (SAS code), Enterprise Miner, Forecast Server

  20. Resources for Real Life Data • Unlike textbook data examples, we all encounter data that are often large and messy • Government Websites • Census Bureau (demographic data) • National Oceanographic and Atmospheric Association (environmental data) • National Highway Traffic Safety Association (transportation data) • National Health and Nutrition Examination Survey (dietary data)

  21. Resources for Real Life Data • Miscellaneous Websites • The Data and Story Library at StatLib • Journal of the American Statistical Association (JASA) Data Archive at StatLib • Gallup News Organization for current events data • Sports organizations for sports related data (More References Listed in Our Paper)
