Key Concepts for Base SAS Certification

The Base SAS Certification exam covers a wide range of topics. Below, we will outline the key concepts you should master to prepare effectively for the exam.

1. SAS System Overview and Environment

Understanding the SAS system environment is the first step toward becoming proficient in SAS. This includes knowing how to access SAS software, the purpose of SAS libraries, and the various components involved in a SAS session. Key areas to focus on include:

• SAS Interface: Understanding how to navigate SAS’s graphical user interface (GUI) and the Enhanced Editor.
• SAS Libraries: How to assign and use libraries to access datasets.
• SAS Datasets: How to create, read, and manipulate datasets.
• SAS Log and Output: Understanding the SAS Log for error messages and the Output window for displaying results.

2. Data Step Programming

The Data Step is the heart of the SAS programming language. In this section of the exam, you’ll be expected to manipulate data effectively. Focus on the following concepts:

• Creating Datasets: Learn how to import data from various formats, create new datasets, and define variable attributes.
• Conditional Statements: Understanding IF-THEN/ELSE logic, looping constructs (DO), and conditional processing.
• Data Transformations: Mastering the use of functions to modify variables, including character functions (e.g., UPCASE, SUBSTR) and numeric functions (e.g., ROUND, SUM).
• Merging Datasets: Learn how to combine data from different sources using MERGE and SET statements.

3. SAS Procedures (PROCs)

SAS Procedures (PROCs) are essential tools for analyzing and summarizing data. A few key PROC steps you should familiarize yourself with are:

• PROC PRINT: Used to display data in tabular form.
• PROC FREQ: For summarizing categorical data (e.g., frequency distributions).
• PROC MEANS: For summarizing numeric data (e.g., calculating mean, standard deviation).
• PROC SORT: For sorting datasets based on variables.
• PROC TRANSPOSE: For reshaping datasets.

4. Handling Missing Data

Dealing with missing data is a crucial part of data analysis. The exam will test your ability to identify, handle, and impute missing values in datasets. Topics to cover include:

• Identifying Missing Values: Understand how to check for missing values using special missing values (e.g., . for numeric and ‘ ‘ for character variables).
• Handling Missing Values: Learn methods for replacing missing data using techniques like IF statements and imputation techniques.
• Dropping Missing Data: Understanding when and how to exclude or drop observations with missing values.

5. SAS Functions and Formats

Mastering SAS functions and formats is essential for manipulating data and performing calculations. Focus on:

• Character Functions: Such as TRIM, UPCASE, and SUBSTR for string manipulation.
• Numeric Functions: Learn how to use functions like SUM, MEAN, ROUND, and ABS for numerical computations.
• Date Functions: Understanding SAS date formats and functions like TODAY(), DATEPART(), and INTNX().

6. Output Delivery System (ODS)

The Output Delivery System (ODS) is used for customizing and formatting output. For the certification exam, you need to be able to:

• Generate Output: Know how to use ODS statements to control where and how results are displayed or saved.
• ODS Destinations: Understand how to send results to different output formats (e.g., HTML, PDF, RTF).
• ODS Styles: Learn how to apply styles to your reports to make them more presentable.

7. Basic Data Analysis

SAS provides several tools for performing basic data analysis, which is key to the exam. You should cover:

• Descriptive Statistics: Using PROC MEANS and PROC FREQ for calculating mean, median, mode, and frequency distributions.
• Basic Data Visualizations: Creating simple charts and graphs using PROC GPLOT and PROC SGPLOT.
• Creating Tables: Using PROC TABULATE to summarize and present data.
