At ValidExamDumps, we consistently monitor updates to the SAS A00-231 exam questions by SAS. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the SAS 9.4 Base Programming - Performance-Based Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by SAS in their SAS A00-231 exam. These outdated questions lead to customers failing their SAS 9.4 Base Programming - Performance-Based Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the SAS A00-231 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Variable Name would have a format of $CHAR15. in the new data set Work. Both. The LENGTH statement only gives the variable Name a predefined maximum length. The correct answer is: $CHAR15 Given the SAS data set WORK.ONE:
X Y Z
- - --
1 A 27
1 A 33
1 B 45
2 A 52
2 B 69
3 B 70

Select one:
SIMULATION
Scenario:
This project will use data set cert.input13. At any time, you may
save your program as program13 in cert\programs.
This data set contains 1001 observations and 2 variables:
o Date1, a numeric variable representing an unformatted
SAS date value. Example: 12001.
o Charnum, a character variable representing a monetary
amount. Example: $50,000.
Write a SAS program that will:
o Save the new data set as results.output13.
o Create a new variable Chdate that converts
the datel variable to a character variable that is in the
format ddmonyyyy, such as 11NOV1992.
o Create a new variable num1 that converts
the Charnum variable to a numeric variable.
What is the average (mean) of the num1 variable for the entire data set?
Enter your numeric answer in the space below (Round your answer to the nearest
integer).
data results.output13;
set cert.input13;
Chdate=put(date 1,date9.);
num 1=input(Charnum,dollar7.);
run;
proc means data=results.output13;
var num 1;
run;

This project will use data set cert.input08a and cert.input08b. At
any time, you may save your program
as program08 in cert\programs.
Both data sets contain a common numeric variable named ID.
Write a program that will use a SAS DATA Step to:
o Combine data sets cert.input08a and cert.input08b by
matching values of the ID variable.
o Write only observations that are in both data sets to a
new data set named results.match08.
o Write all other non-matching observations from either
data set to a new data set named results.nomatch08.
o Exclude all variables that begin with
"ex" from results.nomatch08.
How many observations (rows) are inresults.match08?
Enter your numeric answer in the space below:
SAS code that could be used to solve this project:
proc sort data=cert.input08a out=work.input08a;
by ID;
run;
proc sort data=cert.input08b out=work.input08b;
by ID;
run;
data results.match08 results.nomatch08 (drop=ex: );
merge work.input08a (in=a) work.input08b (in=b);
by ID;
if a and b then output results.match08;
else output results.nomatch08;
run;
proc contents data=results.match08;
run:
proc contents data=results.nomatch08;
run;
The correct answer is: 1200
What is the format for the variableNamein the data setBoth? Select one:
SIMULATION
Scenario:
Open the existing program, program48.sasfrom folder cert\errors. At any time, you may save your corrected program asprogram48incert\programs. This program is intended to:
O Create 3 groups for C var: A-G is Group=1; H-N is Group=2; O-Z is Group=3.
O All variations of the variable should be in the same group, i.e. "A" and "a" should be in Group=1.
O Calculate the average of X and Y by Group. There are multiple errors in the program. These may be syntax errors, logic errors, or problems with the program structure. Logic errors might not produce messages in the log, but will cause the program to produce results different than intended. Correct the errors, run the program, and then use the results to answer the next 2 questions. What is the average (mean) of X for Group=2? Enter your answer to the nearest whole number.
