SAS is a statistical analysis software tool used to conduct anything from traditional analysis of variance and linear regression, through to Bayesian inference and high-performance modeling tools for massive data.
Accessing and using SAS
SAS is accessed via Virtual Laboratory (vLab). For instructions on how to access vLab, head to the vLab page here.
If you have never used SAS before then it is highly recommended that you take a close look at some of the beginner resources below. SAS requires a little know how before it can be used sufficiently.
In this Getting Started with SAS Studio video (9:07"), you get started with programming in SAS Studio. You view a data table, write and submit SAS code, view the log and results, and use interactive features to quickly generate graphs and statistical analyses.
- Learn how to use SAS resources.
- There are a number of free how-to SAS tutorials available online on the SAS Website and on YouTube.
- Explore a variety of resources that can help you use SAS® software.
- For answers to any of your more complex questions, please check out the official SAS knowledge base, or see the official SAS Frequently Asked Questions site.

SAS tables are stored in SAS libraries. A SAS library is a collection of one or more SAS files that are recognized by SAS. In a Microsoft Windows environment, for example, a SAS library is typically a group of SAS files in the same folder or directory. To access a SAS library, you assign it a name. The name is known as the libref, or library reference, and it refers to the physical location of the files. The libref is the nickname that you use to identify libraries in a SAS program.
- Sashelp - a permanent library that contains sample data that you can use. This is a read-only library. You cannot save content to this library.
- Work - a temporary library for files that do not need to be saved. Files in this library are deleted when you close SAS.
