Question 15/34

How does SAS display missing values?

A. a period for missing numeric and a blank for missing character

B. an N for missing numeric and C for missing character

C. a blank for Doth numeric and character missing

D. a blank for missing numeric and a $ for missing character

Correct Answer: A

SAS handles missing values distinctively based on the data type of the variable. For numeric variables, SAS represents missing values with a period (.). For character variables, missing values are represented by a blank space. This handling is crucial for distinguishing between actual data entries and absent data, particularly in statistical calculations and data processing. Options B, C, and D incorrectly describe the representation of missing values in SAS, which does not use special characters like 'N', 'C', or '$' for this purpose.
