NEW QUESTION # 238
You have a dataset called 'sales' with sales data for different products. You want to calculate the mean, standard deviation, and median sales values for each product category, displaying the mean and standard deviation to three decimal places. The dataset has variables 'product_category', 'product_name', and 'sales_amount'. Which PROC MEANS statement correctly performs this task?
Answer: B
Explanation:
The correct answer is option A. The MAXDEC=3 option within the PROC MEANS statement specifies that all statistics, including the mean and standard deviation, should be displayed with three decimal places. The CLASS statement specifies 'product_category' as the grouping variable, and the VAR statement selects 'sales_amount' for analysis. The OUTPUT statement creates a new dataset called 'summary_report' containing the calculated statistics for each product category Option B tries to use a FORMAT statement to control the formatting of the output variables after the PROC MEANS step, which is not the most efficient approach. Option C uses the MAXDEC option with the variable name, but it is not necessary to specify the variable name since it's applying to all variables within the PROC MEANS step. Option D doesn't use the MAXDEC option, so the output will display the default number of decimal places. Option E uses 'product_name' in the CLASS statement, which is incorrect as the grouping should be by 'product_category' Only option A effectively uses the MAXDEC= option within PROC MEANS to achieve the desired output formatting for the mean and standard deviation while correctly grouping by 'product_category' and calculating the median.
NEW QUESTION # 239
You have a dataset named 'SALES' with variables 'Region', 'Product', and 'Quantity'. You want to create a new variable 'SalesValue' based on the following logic: If 'Product' is 'A', then 'SalesValue' = 'Quantity' , 10; If 'Product' is 'B', then 'SalesValue' = 'Quantity' , 15; Otherwise, 'SalesValue' = 'Quantity' , 20. Which code snippet correctly implements this logic in the DATA step?
Answer: D
Explanation:
Option A is the correct code snippet as it uses the correct syntax for the IF-THEN-ELSE statement in SAS. The statement checks the value of the Product' variable and assigns 'SalesValue' accordingly. Option B uses separate IF statements without the ELSE clause, which can lead to incorrect calculations if multiple conditions are met. Option C has redundant IF statements and doesn't consider the 'otherwise' condition. Option D checks for specific values (C and D) in the 'else' clause which might not be appropriate based on the given logic. Option E is the same as option A.
