SAS Tutorials: Exploring Data

Part 1: Viewing the Data

Unlike programs with a graphical user interface, SAS users must take specific actions to view the contents of a dataset. This part of the tutorial covers how to print and preview data in SAS.

Part 2: Descriptive Statistics for Continuous Variables

Before doing any kind of hypothesis testing or model building, you should always examine your data for unusual features or patterns by looking at graphs and descriptive statistics of your data. This section covers how to generate descriptive statistics for continuous numeric variables in SAS.

Part 3: Descriptive Statistics for Categorical Variables

When working with categorical variables, you must still examine your data for unusual trends, patterns, or errors. However, most of the measures that are valid for continuous numeric variables do not apply to categorical variables. In this section, we cover appropriate descriptive statistics for categorical variables.
