pjpnk — Tue, 24 Jul 2018 19:54:46 GMT

Hello - I am stuck here can someone please explain what would be the answer?

Based on this program and the observation shown in the PDV, what variable’s value is assigned to Amount?

PDV

Emp

Pay

Class

Hrs

Amount

Job

Rate

Msg

1201

Contract

data payroll;
   set salaries;
   if PayClass='Monthly' then Amount=Salary;
   else if PayClass='Hourly' then do;
      Amount=HrlyWage*Hrs;
      if Hrs>40 then Msg='CHECK TIMECARD'; 
   end;     
   else Amount=JobRate;
run;

a.)not specified

b.)HrlyWage*Hrs

c.)JobRate

d.)Salary

Any help would be appreciated.

Who asked you this question?

What do you think is the answer and why?

I would go back to the source and verify that the PDV you show is accurate. Since you don't show a variable SALARY in the PDV then something is odd. If there actually is not variable SALARY in the dataset SALARIES then this line would create the variable SALARY with a missing value:

if PayClass='Monthly' then Amount=Salary;

and a note about SALARY was uninitialized.

At which point SALARY = JOBRATE (both missing).

But since the PDV is ALSO missing HrlyWage I suspect that your PDV description is incomplete.

One common test of doubtful questions is to create the "data" and run the code:

data salaries;
   empid='1201';
   payclass='Contract';
   hrs = 30;
   amount=.;
   jobrate=.;
   msg = '   ';
run;
   
data payroll;
   set salaries;
   if PayClass='Monthly' then Amount=Salary;
   else if PayClass='Hourly' then do;
      Amount=HrlyWage*Hrs;
      if Hrs>40 then Msg='CHECK TIMECARD'; 
   end;     
   else Amount=JobRate;
run;

Actually, the PDV doesn't match the program. If it did, it would also contain a spot for Salary and HrlyWage.

That's the source of your confusion. Your link does not select D as the correct answer, but selects C instead. C is correct. The first two IF/THEN conditions are false, so the last statement in the DATA step executes.
