Statistical Analysis System (SAS) Programming Certification Practice Exam 2025 - Free SAS Practice Questions and Study Guide

Creating a temporary data set in SAS involves naming the dataset with a one-level name. In SAS, when you create a dataset without specifying a library, it defaults to the WORK library, which is a temporary library that is automatically deleted at the end of the SAS session or when you close your program.

By giving the dataset a one-level name, SAS recognizes it as a temporary dataset. For example, if you create a dataset like this:

```sas

data mydata;

x = 1;

run;

```

Here, "mydata" becomes a temporary dataset stored in the WORK library. This allows for quick data manipulation without the need to manage permanent datasets, which can be important for session-based analyses or processing.

The other choices do not accurately represent how temporary datasets are created in SAS, making the option of naming the dataset with a one-level name the correct approach for creating temporary datasets in the SAS environment.
