SASInstitute SAS Certified Associate: Programming Fundamentals Using SAS 9.4 A00-215 Prüfungsfragen mit Lösungen (Q169-Q174):

169. Frage
You have a dataset with a variable 'City' containing city names. You want to create a new variable 'State' based on the following logic: , If the city name contains 'New York', assign 'NY' to 'State'. , If the city name contains 'Los Angeles', assign 'CA' to 'State'. , If the city name contains 'Chicago', assign 'IL' to 'State'. , For all other cities, assign 'Other' to 'State'. Which code snippet correctly implements this logic using the FIND function?

Antwort: A

Begründung:
The correct code snippet is option A. Here's the explanation: "FlND(City, 'New York') > checks if the string 'New York' is found within the 'City' variable. If it is, the function returns a positive number indicating the position of the first occurrence. The code then assigns 'NY to 'State'. The code uses similar logic for 'Los Angeles' and 'Chicago'. The "else" statement catches all other cities not matching the specified conditions and assigns 'Other' to 'State' Option B uses a wrong condition for the FIND function, as it should check for a positive return value, not just a non-zero value. Options C and E check for a specific position of the found string, which is not correct. Option D uses the 'ne' operator (not equal to) instead of the '>' operator (greater than), which results in an incorrect check for the FIND function. Only option A correctly implements the desired logic.

170. Frage
You have a dataset with a variable called 'PRODUCT ID' containing numeric values. You want to create a new variable called 'PRODUCT CATEGORY' based on the following logic: ' If 'PRODUCT_ID' is between 100 and 200, then 'PRODUCT CATEGORY' should be 'Electronics'. ' If 'PRODUCT is between 201 and 300, then 'PRODUCT CATEGORY' should be 'Clothing'. ' If 'PRODUCT ID' is outside these ranges, then 'PRODUCT CATEGORY' should be 'Other'. Which of the following SAS code snippets will correctly implement this logic?

Antwort: B,C

Begründung:
The correct answers are A and D. Both options use a series of IF-THEN-ELSE statements to correctly map the 'PRODUCT_ID' values to their corresponding 'PRODUCT_CATEGORY'. Option A utilizes the <= operator for range checks, while Option D uses >= and <= for the same purpose. Option B, while syntactically valid, is not recommended for range checks as it's not the most efficient way to handle this scenario. Option C, while using 'between' keywords, does not properly handle inclusive ranges and is incorrect Option E uses 'if statement within assignment, leading to syntax errors.

171. Frage
You are working with a dataset containing a variable 'START DATE' that stores dates in the format 'YYYY-MM- DD'. You need to create a new variable 'DAYS SINCE START' that calculates the number of days since the start date for each record. Which SAS code snippet correctly achieves this?

Antwort: A

Begründung:
The correct code uses the 'intck' function to calculate the difference in days between the start date and a reference date ('01JAN1960'd). Option D correctly converts the 'START_DATE' variable to a SAS date value using "input(START DATE, yymmdd10.)' before applying 'intck'- Option A is incorrect because it calculates the days from '01 JANI 960'd to 'START_DATE', which is not what the problem requires. Option B uses an incorrect order of arguments for 'intck'- Option C uses 'OIJANI 960'd as a date value, but it doesn't convert 'START DATE' to a SAS date. Option E uses today(), which gives the current date, not a fixed reference date.

172. Frage
Which PROC IMPORT step correctly creates the MYDATA,SALES data set from the SALES.SCV file?

A. proc import data="mydata. sales" dbms=csv
out="mydata.sales;
nun
B. proc import data=mydata.sales dbms=csv
out=mydata.gales; run,-
C. proc import datafile=sales.csv dbms=csv
out-"mydata,sales";
run;
D. proc import datafile="sales.csv" dbms=csv
out-mydata. sales;

Antwort: C

173. Frage
Which statement is true when creating two SAS data sets with a DATA step?

A. Use a PUT statement to output the observations to the appropriate data sets.
B. Use an OUT= option in the WHERE statement to output the observations to the appropriate data sets.
C. Name both data sets in the DATA statement
D. Use a separate SET statement for each data set.

Antwort: D
