Before diving into coding, it’s important to understand how the SAS system works. This includes knowing how to start and interact with SAS, understanding the role of SAS libraries, and being familiar with the SAS Environment.

Key areas to focus on include:

SAS Interface: Understanding how to navigate the SAS environment, including the Enhanced Editor, log window, and output window.
SAS Libraries: Learning how to assign and access libraries, and how datasets are stored and accessed within those libraries.
SAS Log and Output: Knowing how to interpret SAS logs and output results, and how to identify and fix errors in your code.

2. Data Step Programming

One of the most fundamental concepts in SAS programming is the Data Step. You’ll need to be able to use this powerful tool to create datasets, manipulate data, and perform transformations.

Key topics to focus on include:

Creating Datasets: Learn how to read in raw data, assign variable attributes, and output new datasets.
Conditional Statements: Using IF-THEN/ELSE statements for data manipulation.
Merging and Concatenating Datasets: Learn how to use MERGE and SET statements to combine datasets.
Data Transformations: Master using functions for modifying or calculating new variables.

3. SAS Procedures (PROCs)

SAS Procedures (PROCs) are used to perform data analysis and reporting tasks. The most important procedures to master for the exam include:

PROC PRINT: Displaying data.
PROC FREQ: Producing frequency tables.
PROC MEANS: Calculating summary statistics like mean, median, and standard deviation.
PROC SORT: Sorting data.
PROC TRANSPOSE: Reshaping data.
PROC FORMAT: Creating custom formats.

4. Handling Missing Data

Managing missing data is essential for reliable analysis. You should know how to identify, handle, and deal with missing values.

Key concepts to focus on:

Identifying Missing Data: Using SAS notation to detect missing values for both numeric (.) and character variables (‘ ‘).
Replacing Missing Values: How to use IF-THEN logic to fill in missing values or exclude them from analysis.
Imputing Missing Data: Exploring techniques like mean imputation or other methods to handle missing data.

5. SAS Functions and Formats

SAS includes a wide range of functions that can help you manipulate and analyze data. Key functions to study include:

Character Functions: Such as SUBSTR, UPCASE, and TRIM.
Numeric Functions: Including SUM, MEAN, and ROUND.
Date Functions: Mastering functions like TODAY(), DATEPART(), and INTNX().
Custom Formats: Creating and applying custom formats using PROC FORMAT.

6. Output Delivery System (ODS)

The Output Delivery System (ODS) is critical for generating reports. You should understand:

Generating Reports: How to use ODS statements to produce output in various formats (e.g., HTML, PDF, RTF).
ODS Destinations: Controlling where and how the output is displayed or stored.
ODS Styles: Applying styles to reports to improve their presentation.
