Question #: 44
Topic #: 13

[All A00-215 Questions]

Given the following code:

Which variables are created with the BY statement?

AState. First and State. Last

BFirst. State and Last. State

CFirst_State and Last_State

DFirst. and Last.

Show Suggested Answer

Suggested Answer: A

In SAS, when you use a BY statement in a DATA step, SAS creates two temporary variables for each variable listed in the BY statement: one to indicate the first occurrence (FIRST.variable) and another to indicate the last occurrence (LAST.variable) of the value within the BY-group. Given the provided code and assuming that State is the variable used in the BY statement, SAS will create First.State and Last.State. Thus, option A is correct.

B doesn't make sense, it's not how variable naming works.

I thought the BY statement only created variables for the first and last names, but now I'm questioning if that's right.

I feel like it's definitely First_State and Last_State, but I might be mixing it up with another example we did in class.

I remember practicing a similar question where the BY statement defined new variables, but I can't recall the exact names.

I think the BY statement creates variables based on the grouping, but I'm not sure if it's First and Last or something else.

I'm going to carefully analyze the code and the variable naming conventions to determine the right answer. The key is understanding how the BY statement works in this context.

Wait, I'm confused. The options mention State. First, State. Last, First. State, and Last. State. I'm not sure which one is correct.

Okay, I think I've got this. The BY statement is creating variables based on the First. and Last. prefixes, so the answer is likely D. First. and Last.

Hmm, I'm a bit unsure about this one. The BY statement can create some tricky variable names, so I'll need to think it through step-by-step.
