Question

Which procedure would you use to see the distinct values of Flower_Type with a count and percentage for each?

1) PROC FREQ
2) PROC MEANS
3) PROC SORT
4) PROC SUMMARY

Answer 1

To view distinct values of Flower_Type with a count and percentage, use PROC FREQ in SAS. It provides frequency counts and percentages, which are essential for data frequency analysis.

Step-by-step explanation:

To see the distinct values of Flower_Type with a count and percentage for each, the appropriate procedure to use is 1) PROC FREQ. This procedure in SAS (Statistical Analysis System) provides the frequency counts and the corresponding percentages of the categories of a categorical variable. PROC FREQ generates tables that display frequency, relative frequency, and cumulative relative frequency which are fundamental in understanding how often each category of data appears.

An example of a simple PROC FREQ code would be:

PROC FREQ DATA=mydata;
TABLES Flower_Type / OUT=FreqOut NOPRINT;
RUN;
After running the code, the output dataset 'FreqOut' will contain the frequency and percentage of each unique Flower_Type found in the dataset 'mydata'. Procedures like PROC MEANS or PROC SUMMARY are more suitable for summary statistics of quantitative data and PROC SORT is used for sorting data rather than for frequency distribution analyses.
