Sample SAS Base Programming Practice Questions

Try these sample questions to review concepts for the SAS Base Programming exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 131+ question experience with AI tutoring.

1What SAS statement assigns a library reference name to a physical location on disk?
A.DATA
B.LIBNAME
C.FILENAME
D.PROC
Explanation: The LIBNAME statement associates a logical name (libref) with a physical location. For example, LIBNAME mylib "/path/to/data"; allows referencing datasets as mylib.dataset_name.
2Which PROC is used to examine the contents and structure of a SAS data set?
A.PROC PRINT
B.PROC CONTENTS
C.PROC MEANS
D.PROC FREQ
Explanation: PROC CONTENTS displays metadata about a SAS dataset including variable names, types, lengths, formats, labels, number of observations, and creation date. It is essential for understanding dataset structure.
3In a SAS DATA step, what does the SET statement do?
A.Creates a new empty dataset
B.Reads observations from an existing SAS dataset into the Program Data Vector (PDV)
C.Sets variable values to missing
D.Configures system options
Explanation: The SET statement reads observations one at a time from an existing SAS dataset into the Program Data Vector (PDV). It is the primary mechanism for reading SAS datasets in the DATA step, and multiple SET statements can be used for interleaving or one-to-one merging.
4What is the correct syntax for reading a delimited text file in a SAS DATA step?
A.PROC IMPORT DATAFILE="file.csv"
B.INFILE "file.csv" DLM=","; INPUT var1 var2 var3;
C.READ "file.csv" DELIMITER=","
D.LOAD DATA FROM "file.csv"
Explanation: The INFILE statement specifies the external file location and the DLM= option defines the delimiter. The INPUT statement names the variables and their types. Together they read raw delimited data into SAS.
5What is the difference between character and numeric variables in SAS?
A.Character variables store text up to 32,767 bytes; numeric variables store numbers as 8-byte floating point by default
B.Character variables are always shorter than numeric variables
C.Numeric variables can store text if formatted correctly
D.There is no difference in SAS
Explanation: Character variables store text strings with a maximum length of 32,767 bytes. Numeric variables are stored as 8-byte (64-bit) double-precision floating point numbers by default, which can represent integers exactly up to 2^53.
6How do you sort observations in a SAS dataset?
A.Use the ORDER BY clause in a DATA step
B.Use PROC SORT with a BY statement specifying the sort variables
C.Use PROC PRINT with an ORDER option
D.Sort manually by rearranging rows
Explanation: PROC SORT reorders observations in a SAS dataset. The BY statement specifies which variables to sort by and in what order (ascending by default, DESCENDING keyword for reverse). The OUT= option creates a new sorted dataset.
7What does the MERGE statement do in a SAS DATA step?
A.Combines variables from two datasets side by side
B.Combines observations from multiple SAS datasets horizontally based on common BY variables
C.Appends rows from one dataset to another
D.Calculates the median of merged values
Explanation: The MERGE statement combines observations from two or more datasets horizontally. When used with a BY statement, it performs a match-merge, joining observations with matching BY variable values from each dataset.
8What is the purpose of the IF-THEN/ELSE statement in a SAS DATA step?
A.To define a new procedure
B.To conditionally execute statements based on whether a logical expression is true or false
C.To create a loop
D.To format output
Explanation: IF-THEN/ELSE provides conditional processing in the DATA step. If the condition is true, the THEN clause executes. If false, execution passes to the ELSE clause (if present). Multiple conditions can be chained with ELSE IF.
9How do you create a new variable in a SAS DATA step?
A.Use the CREATE VARIABLE statement
B.Use an assignment statement: new_var = expression;
C.Use PROC NEWVAR
D.Declare the variable with the VAR keyword
Explanation: New variables are created implicitly through assignment statements in the DATA step. For example, total = price * quantity; creates a new numeric variable called total. SAS automatically determines the variable type from the expression.
10What is the purpose of the RETAIN statement in a SAS DATA step?
A.To keep the dataset in memory
B.To prevent a variable from being reset to missing at the beginning of each iteration of the DATA step
C.To retain the output dataset after the program ends
D.To keep selected observations
Explanation: By default, SAS resets variables created in the DATA step to missing at the start of each iteration. The RETAIN statement prevents this reset, allowing a variable to keep its value across iterations. This is essential for running totals and cumulative calculations.
