Question

Which listing output could be produced by the following code?

proc print data=tropical(obs=3);
where Plant='Orchid';
var Plant Location;
run;
a.
Obs Plant Location
1 Orchid Hawai'i
2 Orchid Thailand
8 Orchid Hawai'i
b.
Obs Plant Location
1 Orchid Hawai'i
2 Orchid Thailand
3 Anthurium Hawai

Answer 1

The correct listing is option 'a', which shows three observations of the Plant 'Orchid' in different locations. Option 'b' is incorrect because it lists a different plant ('Anthurium'), which contravenes the WHERE clause filtering only for the 'Orchid' plant in the code.

Step-by-step explanation:

The code presented is written in SAS, which is a software suite used for advanced analytics, multivariate analyses, business intelligence, data management, and predictive analytics.

The PROC PRINT statement is used to produce a listing of a SAS dataset, and this specific code snippet provides instructions to list only the first 3 observations (obs=3) where the variable Plant is equal to 'Orchid'. Additionally, it specifies that only the variables Plant and Location should be included in the output.

Given the WHERE clause filtering for the Plant 'Orchid', the result shown in option 'a' is correct because it only lists observations where the Plant value is 'Orchid'. The incorrect option 'b' has an entry with a different plant ('Anthurium'), which should not be there due to the where clause in the code.
