What are SAS formats used for?

SAS formats are primarily utilized to control how data values are displayed, which directly impacts how the information is interpreted by users during data presentation and analysis. Formats can modify the appearance of numeric values, such as displaying them with a specific number of decimal places or as currency. They can also affect character variables, allowing for the application of specific styles, such as uppercase formatting or masking characters. This aspect of formatting is crucial as it enhances the readability and interpretability of the data.

For instance, using the dollar format to present monetary values can help users immediately recognize figures as currency, while date formats can help in understanding time-associated data more effectively. Thus, formats play a significant role in statistical reporting and data visualization strategies within SAS, ensuring that data is not only accurate but also accessible and understandable to the intended audience.
