I am teaching a class, Introduction to SAS (MEDB 5507). Here is the syllabus for Spring<U+00A0> Semester 2018.
MEDB 5507: Introduction to SAS
A working knowledge of statistical software is a vital skill for anyone involved in quantitative research. This course will introduce data management, simple descriptive statistics, and basic graphical display using the SAS software package. Students will develop the fundamental skills needed to prepare datasets for analysis, and to conduct simple descriptive and graphic analyses and report those analyses.
1.1 Course Description
This course will to provide a working familiarity with SAS. Students are not expected to have advanced programming or statistical analysis skills other than the ability to create and modify text files. A basic understanding of statistical terminology and a working familiarity with computer-based data files (e.g., Excel) is necessary. The class will introduce basic methods for data import, data management, simple graphics, and basic statistical analysis. This class will not cover advanced statistical methods, but will provide you with a firm foundation to address these areas in your advanced statistics classes or in your research efforts, including thesis/dissertation research.
1.2 Student Learning Objectives
At the completion of this course, students will be able to:
- Prepare and manipulate datasets for analysis in SAS.
- Conduct simple descriptive and graphic analyses of data in SAS.
- Prepare a report with a summary of analyses conducted in SAS.
1.3 Course Framework
This class will be taught as a self-paced, asynchronous online course. The instructor will provide datasets and instructions for running various coding functions within SAS. You will apply these functions to import datasets, manipulate these datasets, and produce basic summaries of these datasets. As the final project of the class, you will produce an independent analysis on a dataset of your own choice that demonstrates the coding techniques and skills that were covered in the course.

My email contact information is at http://www.pmean.com/contact.html. The preferred email address is the UMKC account, but any of these email addresses are fine. I do not check email on my days off from work, so please don’t worry if you don’t get an immediate response. If you have not heard back by 48 hours, please feel free to contact me again.
You are also welcome to call me. My office number is 816-235-6617 and my cell phone number is 913-912-2076.
2.3 Discussion forum
Before you contact me by email or telephone, consider posting your problem or question on the Blackboard discussion board. Others will benefit from the exchange. You are welcome, however, to discuss problems and ask questions via email or telephone if you prefer.
2.4 Office hours
You can get help for many of your questions by email, but sometimes a face-to-face appointment is needed. I am part-time at UMKC and hold two other part-time jobs, so I cannot hold regular office hours. I am more than happy to meet with you face-to-face by appointment. Because of child care responsibilities, I generally cannot meet prior to 9am (10am on Thursdays) and I have to leave most days by 2pm. I have a lot more flexibility for meeting via telephone.
3. Course structure
This class is a self-paced, asynchronous online course. Course material is organized into six parts. In order to achieve learning objectives, students need to review provided course materials, including recorded lectures. During the lectures, the instructor will provide coding examples to demonstrate application of SAS, and then students will have hands on programming experience with support and feedback from the instructor. As the final project of the class, students will independently apply these skills to their own dataset and produce an analysis of these data.
3.1 Student projects
Students will be presented with instructions on using SAS functions and/or syntax files and be shown how to apply those to a provided dataset. Under the supervision of the instructor, students will apply these skills to a different provided dataset. At the end of each part, students will turn in material that documents their work process and results, and a brief written interpretation of the work done for that assignment. For the final project, students will use a new dataset of their own choosing, import that dataset, manipulate it as needed, and produce a statistical report using at least one graphical display and at least one descriptive statistical method. The final project must include a written explanation of the results. The dataset you work with for the final project should include four or more variables of which at least two variables are continuous measures and at least two variables are categorical measures.
This course is graded as Pass / Fail. In order to receive a passing grade, the student must successfully complete the assignments, including the assignment for the final project that includes work using a new dataset provided in the course or your own dataset. This work must be completed and submitted to the instructor by Friday, April 6, 2018 in order to get credit for the course.
There is NO required textbook for this class. The following books are possible resources you might want to purchase for your future work with SAS.
- Delwiche & Slaughter. The Little SAS Book. 5th Edition. SAS Institute Inc., Cary, NC.
- Cody. Learning SAS by Example : A Programmer’s Guide. SAS Institute Inc., Cary, NC.
- Cody. SAS Statistics by Example. SAS Institute Inc., Cary, NC.
4.2 SAS software
This course will use SAS for all assignments and the final project. Students will have access to the SAS program either directly on a computer that has SAS installed, through UMKC Remote Labs (http://www.umkc.edu/is/remotelabs/), or through SAS resources (refer below to SAS University under Other Resources). The Department of Biomedical and Health Informatics has student computer workstations available that can be used by arrangement.
Please note that when you are logged onto Remote Labs, it will probably be difficult to have direct access to a drive (USB or hard drive) on the computer you are sitting at (the remote system has a hard time seeing these local devices/ports). You will, however, be able to save files to your Q drive space. When using the UMKC Remote Labs resource, I recommend that you save your course files on your Q drive space or use cloud storage. The Q drive space is part of the UMKC network and your space is automatically mapped when you log onto the UMKC system. If you have questions about how to access this directory, contact UMKC Information Services (816-235-2000). From the Q drive, files can be copied/moved to other storage locations/devices.
4.2 SAS University
SAS offers a product, SAS University, that is free to anyone as long as it is not used for commercial purposes. Details are available at http://blog.pmean.com/sas-university/.

5. Course outline
For each part of the course, the instructor will provide a recorded lecture that shows a demonstration of SAS coding and program execution. In addition, in the Course Content area of the course Blackboard site students will have a Course Outline document (MEDB 5507_Intro to SAS_Course Outline_Notes & Assignments_FS2017.pdf) that provides detailed notes and information on each assignment. Also loaded in the Course Content area will be data files that are not publicly available, descriptions of these data files, and the SAS program files used for the recorded coding examples. These coding files can be used as the starting point for your own coding if desired; they can be edited using the SAS program editor, or edited using a text editor and copied into the SAS program editor. It is recomended that you copy these files to a local device (i.e., hard drive or USB drive) to simplify working with the information.
If you are trying to work in SAS at the same time as viewing the recorded lectures, it is recommended that you use a system that will allow you to follow along with the recordings and make notes on the coding as needed. If you are using a system that has 2 monitors, this can be accomplished by playing the recording on one screen and doing other operations on the other screen.
A Discussion Board area (Discussion Forum, Intro to SAS – Questions & Answers) is established in the course Blackboard site in order to have a space for questions and answers that will be available to all students. To post a question on this forum,
Note – if you are getting a SAS error message you don’t understand, you can copy the error message into the Description box. If you want a section of coding reviewed because you are having a problem with it, you can also copy the text into the Description box.<U+00A0> The instructor will review and respond to items posted on the Discussion Board on a regular basis. If you have not gotten a response within a day or two, send an email to the instructor asking her to review your question in the discussion forum.
