Example: “There are four main types of data that can be analyzed using SAS:
-Numeric data: This type of data includes information that can be quantified, such as age, weight, or income. Numeric data can be further divided into two subcategories: discrete and continuous. Discrete data can only take on certain values (such as whole numbers), while continuous data can take on any value within a range.
-Character data: This type of data includes text strings. Character data can be further divided into two subcategories: fixed-length and variable-length. Fixed-length character data has a set number of characters, while variable-length character data can have varying numbers of characters.
-Date/time data: This type of data includes information about dates and times. Date/time data can be further divided into two subcategories: date and time. Date data includes information about the year, month, and day, while time data includes information about the hour, minute, and second.
-Binary data: This type of data includes information that can only be represented as either 0 or 1 (on or off). Binary data is often used to represent images or other non-textual information.”

How does SAS handle missing values?

There are a few reasons why an interviewer might ask this question:

1. To test the interviewee's knowledge of SAS programming.

2. To see if the interviewee is familiar with the different options for handling missing values in SAS.

3. To gauge the interviewee's understanding of how SAS deals with missing values internally.

It is important to know how SAS handles missing values because it can impact the results of any analyses that are conducted on the data. If the wrong method is used to handle missing values, it can lead to inaccurate results.

Example: “SAS uses a concept called missing values to handle data that is incomplete or unavailable. When SAS encounters a missing value, it uses a special missing value indicator to represent the value in calculations. This allows SAS to continue processing the data even though some values are missing.”

What are the different SAS procedures used for data analysis?

The interviewer is asking this question to gauge the SAS Developer's level of experience with the SAS software. It is important to know the different SAS procedures because they can be used to perform a variety of tasks, such as data manipulation, data analysis, and report generation. By knowing the different procedures, the SAS Developer can select the most appropriate one for the task at hand.

Example: “There are many different SAS procedures that can be used for data analysis, depending on the specific needs of the project. Some of the most commonly used SAS procedures for data analysis include PROC MEANS, PROC FREQ, PROC UNIVARIATE, and PROC GLM.”

What are the different SAS functions used for data analysis?

There are many different SAS functions that can be used for data analysis, and it is important for a SAS developer to be familiar with as many of them as possible in order to be able to effectively analyze data.

Example: “There are a number of SAS functions that can be used for data analysis, including:
- MEANS: Used to calculate the mean or average of a numeric variable.

What are the different types of SAS programming statements?

There are a few reasons why an interviewer might ask this question:

1. To gauge the SAS Developer's understanding of the different types of SAS programming statements. It is important for a SAS Developer to understand the different types of statements because they will need to use them when writing code.

2. To see if the SAS Developer can explain the different types of statements in detail. This is important because the SAS Developer will need to be able to explain their code to others.

3. To determine if the SAS Developer is familiar with all of the different types of statements. This is important because the SAS Developer will need to be able to use all of the different types of statements when writing code.

Example: “There are four different types of SAS programming statements: data, proc, run, and quit. Each type of statement has a specific purpose and is used to perform different tasks within SAS.

Data statements are used to load data into SAS from external sources, such as text files or databases. Proc statements are used to process data within SAS, such as sorting or calculating summary statistics. Run statements are used to execute SAS programs. Quit statements are used to end the SAS session.”

What are the different types of SAS programming options?

There are four different types of SAS programming options:

1. SAS DATA Step

2. SAS Macro Language

3. SAS SQL Procedure

4. SAS Graph Procedure

Each of these options has its own strengths and weaknesses, and it is important for a SAS developer to be familiar with all of them in order to be able to choose the best option for each particular situation.

Example: “There are four main types of SAS programming:
1. Data step programming
2. PROC SQL programming
3. Macro programming
4. Output Delivery System (ODS) programming”

What are the different types of SAS programming errors?

There are different types of SAS programming errors because there are different types of programming languages. Each language has its own set of rules and guidelines. If a programmer does not follow the rules for a particular language, they can produce errors.

It is important for an interviewer to ask about different types of SAS programming errors because it shows that they are interested in understanding how the candidate works through their programming mistakes. It also allows the interviewer to gauge the depth of the candidate's SAS knowledge.

Example: “There are three types of SAS programming errors:
1. Syntax errors
2. Runtime errors
3. Logic errors

Syntax errors occur when the SAS program is not written correctly according to the SAS syntax rules. For example, missing a semicolon at the end of a statement or using incorrect spelling for a SAS keyword. These errors will be flagged by SAS when you attempt to run the program and will need to be fixed before the program can be executed successfully.

Runtime errors occur when the SAS program is syntactically correct but fails to execute due to an error in the code. For example, trying to divide by zero or referencing a variable that has not been assigned a value. These errors will cause SAS to stop execution of the program and will generate an error message indicating where the problem occurred.

Logic errors are errors in the logic of the SAS program that do not cause SAS to generate an error message. For example, forgetting to include a WHERE clause in a DATA step that filters out observations that should not be processed. These types of errors can be difficult to find because they do not generate an error message from SAS.”

What are the different types of SAS programming notes?

There are different types of SAS programming notes because there are different types of SAS programming. The most common type of SAS programming is data step programming, which is used to manipulate data sets. There are also other types of SAS programming, such as macro programming and SQL programming. Each type of SAS programming has its own set of rules and syntax.

It is important for an interviewer to ask this question because it shows that they are familiar with the different types of SAS programming. This question also allows the interviewer to gauge the interviewee's knowledge of SAS programming.

Example: “There are four types of SAS programming notes:

1. NOTE: This type of note is used to provide information about the SAS program. It does not produce any output.

2. WARNING: This type of note is used to provide information about potential problems that could occur when running the SAS program. It does not produce any output.

3. ERROR: This type of note is used to provide information about an error that has occurred when running the SAS program. It produces an error message and halts execution of the program.

4. FATAL: This type of note is used to provide information about a fatal error that has occurred when running the SAS program. It produces an error message and terminates execution of the program.”

What is the structure of a SAS program?

The interviewer is asking this question to gauge the SAS Developer's understanding of the SAS programming language. The structure of a SAS program is important because it determines how the program will be executed and how the data will be processed.

Example: “A SAS program is typically divided into two parts: a data step and a proc step. The data step reads in data, processes it, and creates one or more SAS data sets. The proc step uses those data sets to generate results.”

What are the different types of SAS datasets?

There are different types of SAS datasets because there are different types of data that can be stored in a SAS dataset. The type of data that is stored in a SAS dataset determines the type of SAS dataset.

The most common type of SAS dataset is a data set. A data set can contain any type of data, including numeric data, character data, and binary data. A SAS dataset can also contain other types of data, such as images and text.

The type of SAS dataset that is used depends on the type of data that is being stored. For example, if the data is numeric, then a numeric SAS dataset would be used. If the data is character, then a character SAS dataset would be used.

Example: “There are two types of SAS datasets:
1. Data library: A data library is a collection of SAS data files that are stored in a specified location.
2. Work library: A work library is a temporary location where SAS stores files during the SAS session.”

What are the different types of SAS files?

There are three different types of SAS files: SAS data files, SAS program files, and SAS log files. Each type of file has a different purpose and is used in different ways.

SAS data files store data that can be used by SAS programs. SAS program files contain the code that SAS uses to process data. SAS log files contain information about the SAS session, such as what SAS programs were run and what errors occurred.

It is important for a SAS developer to know the different types of SAS files because each type of file has a different purpose. Knowing the purpose of each type of file can help the developer write better code and troubleshoot problems more effectively.

Example: “There are four different types of SAS files:
1. Data files
2. Program files
3. Macro files
4. Output files”

What are the different types of SAS formats?

SAS formats are used to control the way data values are displayed. For example, a numeric value can be displayed as a currency amount, or a date can be displayed in various formats.

SAS formats are important because they can be used to control how data is displayed to the user. This can be important for making sure that data is displayed in a way that is easy to understand and interpret.

Example: “The different types of SAS formats are:
1. Character
2. Numeric
3. Date
4. Time
5. Datetime”

What are the different types of SAS informats?

There are many reasons why an interviewer might ask this question to a SAS developer. It could be to gauge the SAS developer's level of experience, to see if they are familiar with the different types of SAS informats, or to assess their ability to work with data in different formats.

SAS informats are important because they allow SAS developers to read and write data in different formats. This can be important when working with data from different sources, or when working with data in different languages.

Example: “The different types of SAS informats are:

1. Character Informats: These informats are used to read in character data. Examples of character informats include the $CHAR informat and the $VARYING informat.

2. Numeric Informats: These informats are used to read in numeric data. Examples of numeric informats include the BEST12. informat and the COMMAw.d informat.

3. Date/Time Informats: These informats are used to read in date and time data. Examples of date/time informats include the DATE9. informat and the TIME5. format.”
