Your Turn to Practice

The only way to really learn the application of SAS and statistical analysis applications for research problems is to work through examples and scenarios. Below are some examples of very simple SAS programs that you can use to practice with SAS. We recommend making notes about each line and section of the code to help you understand what is happening. Try to focus on explaining each command in your own terms, the importance of the section, and what you are telling SAS to do. Print the output that you generate and explain what you have produced.
