# Example 1: Computing Specific Descriptive Statistics

 Features: PROC MEANS statement options: statistic keywords FW= VAR statement Data set: CAKE

### Details

This example does the following:
• specifies the analysis variables
• computes the statistics for the specified keywords and displays them in order
• specifies the field width of the statistics

## Program Description

Set the SAS system options. The NODATE option suppresses the display of the date and time in the output. PAGENO= specifies the starting page number. LINESIZE= specifies the output line length, and PAGESIZE= specifies the number of lines on an output page.
`options nodate pageno=1 linesize=80 pagesize=60;`
Create the CAKE data set. CAKE contains data from a cake-baking contest: each participant's last name, age, score for presentation, score for taste, cake flavor, and number of cake layers. The number of cake layers is missing for two observations. The cake flavor is missing for another observation.

;```
Specify the analyses and the analysis options. The statistic keywords specify the statistics and their order in the output. FW= uses a field width of eight to display the statistics.
`proc means data=cake n mean max min range std fw=8;`
Specify the analysis variables. The VAR statement specifies that PROC MEANS calculate statistics on the PresentScore and TasteScore variables.
`   var PresentScore TasteScore;`
Specify the title.
```   title 'Summary of Presentation and Taste Scores';
run;```
