Which statement correctly describes the ROLE of the FORMAT statement?

The FORMAT statement in SAS is primarily used to display the values of variables according to specified formats. This means that when you apply a FORMAT to a variable, it will change how that variable’s values are presented in the output, making it easier to interpret the data. For instance, you might use formats to display dates in a more readable format, such as converting '20230101' to '01JAN2023', or to format numerical values with commas or currency symbols.

This capability enhances the readability of reports and outputs, allowing for more accurate data interpretation and better communication of results. The FORMAT statement does not alter the actual data stored in the dataset but rather affects how that information is seen when it is printed or outputted.

Other options focus on functionality that does not align with what the FORMAT statement does. For example, eliminating unwanted variables pertains to data processing rather than formatting. Standardizing data types involves ensuring compatibility for analysis, which is different from the formatting of display. Sorting datasets alphabetically is related to organizing data rather than how it's displayed. Thus, this makes the chosen answer the most accurate in describing the role of the FORMAT statement.
