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Other certification materials providers often include outdated or removed questions by SAS in their SAS A00-231 exam. These outdated questions lead to customers failing their SAS 9.4 Base Programming - Performance-Based Exam exam.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:

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. Enter your numeric answer in the space below:
SIMULATION
Scenario:
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.nomatch08?
proc sort data=cert.input08b out=work.input08b;
by ID;
run:
SAS code that could be used to solve this project:
proc sort data=cert.input08a out=work.input08a;
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: 2
SIMULATION
Scenario:
Open the existing program, program44.sasfrom folder cert\errors. At any time, you may save your corrected program asprogram44incert\programs. This program is intended to:
O Create a new data set using thecert.input44set as input
O Drop variables:bp_status, weight_status, andsmoking _status.
o Create a new column,chol_status, based on the following values of cholesterol:
less than 200: "Safe"
200-239: "High - Borderline"
240 and higher: "High" oShould not calculatechol_statusfor missing cholesterol values 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 3 questions. How many variables are in thework. outdata set? Enter your numeric answer in the space below:
Given the following SAS data set WORK.CLASS:
Name Gender Age
Anna F 23
Ben M 25
Bob M 21
Brian M 27
Edward M 26
Emma F 32
Joe M 34
Sam F 32
Tom M 24
The following program is submitted: data WORK.MALES WORK.FEMALES(drop=age); set WORK.CLASS; drop gender; if Gender="M" then output WORK.MALES; else if Gender="F" then output WORK.FEMALES; run; How many variables are in the data set WORK.MALES?
