This is the first SAS workshop in a two-part series. This interactive workshop will introduce users to the SAS system. Applied, hands on, examples using real data will be used. NOTE: This workshop is aimed at people who do not have experience using the SAS system. Those who have used SAS in the past may find this workshop too foundational and are encouraged to attend our forthcoming advanced SAS sessions.

Workshop Topics:

• Reading data into SAS
• Conducting basic data cleaning and recoding
• Using basic SAS procedures (e.g., PROC CONTENTS, PROC PRINT, PROC FREQ) to view and understand data.
• PROC FREQ, PROC UNIVARIATE, and PROC MEANS will be demonstrated to complete basic descriptive statistics.
• An introduction to bivariate statistics in SAS.

Prerequisites: No prior experience with SAS is required. Basic understanding of univariate and bivariate statistics is helpful but not required.

SAS 2: Data Analysis

This is the second SAS workshop in a two-part series. In this interactive workshop, SAS users will go beyond the basics to develop comfort with more advanced statistical analyses using the SAS system. Applied, hands on, examples using real data will be used. NOTE: Basic knowledge of the SAS system will be helpful for those who want to participate in the applied portion of the workshop.

Workshop Topics:

• Conducting bivariate and multivariable analyses using SAS procedures like PROC FREQ, PROC TTEST, PROC ANOVA, PROC GLM, PROC LOGISTIC, and PROC REG.
• Best practices for checking statistical assumptions, selecting appropriate statistical procedures, and reporting and visualizing results will be discussed.

Prerequisites: Basic knowledge of the SAS system will be helpful for those who want to participate in the applied portion of the workshop. Basic understanding of bivariate and multivariable statistics is helpful.
