What statement can be used to complete the SAS program for the desired report?

The successful completion of the SAS program for generating the desired report involves using the appropriate combination of statements to organize and display data. The statement that combines the IDs, the BY grouping, and the variables to be summarized is crucial for ensuring that the report reflects the intended structure.

In the correct choice, using "id location" specifies that the location is the identifier for the output, which helps to label the observations in the report appropriately. This is particularly useful in summarizing data because it allows for a clearer understanding of which data belongs to which location.

The "by location" statement is essential as it instructs SAS to group the data by the location before performing any subsequent operations. This grouping ensures that all computations or summaries, such as those defined in the "var" statement, are carried out within each specified location, thus maintaining the context of the report.

Finally, the "var grade students teachers" part indicates the specific variables that will be included in the reports. This allows for a focused analysis on these variables while disregarding any others that may not be relevant to the report.

This combination effectively creates a detailed, organized report that clearly communicates the relationships and values for each location. The other choices mix or misplace the necessary components, leading to either
