## How do you sort proc freq?

Syntax. PROC FREQ DATA=sample ORDER=freq; TABLE State Rank; RUN; The ORDER=freq option in the first line of the syntax tells SAS to order the values in the table in descending order.

## What does the missing option do in Proc Freq?

PROC FREQ treats missing BY variable values like any other BY variable value. The missing values form a separate BY group. If an observation has a missing value for a variable in a TABLES request, by default PROC FREQ does not include that observation in the frequency or crosstabulation table.

**How do you suppress frequency in Proc Freq?**

Suppressing the Displayed Output Use NOPRINT in the PROC FREQ statement to suppress all displayed output as well as the Output Delivery System. Use NOPRINT in the TABLES statement to suppress frequency and crosstabulation tables but still display the requested statistics.

**What does the tables Statement do in the PROC FREQ step?**

The TABLES statement requests one-way to n-way frequency and crosstabulation tables and statistics for those tables. If you omit the TABLES statement, PROC FREQ generates one-way frequency tables for all data set variables that are not listed in the other statements.

### What type of data is generally appropriate to be analyzed with PROC FREQ?

Proc FREQ is widely used to analyze healthcare datasets and demographic databanks that contain specific information about individuals and their activities. Any dataset that requires analysis on an individual or multi-variable level can be manipulated with this procedure.

### How do you get Proc Freq output in a dataset?

PROC FREQ produces two types of output data sets that you can use with other statistical and reporting procedures. You can request these data sets as follows: Specify the OUT= option in a TABLES statement. This creates an output data set that contains frequency or crosstabulation table counts and percentages.

**What is the difference between proc means and proc freq?**

PROC MEANS is used to calculate summary statistics such as mean, count etc of numeric variables. It requires at least one numeric variable whereas Proc Freq does not have such limitation. In other words, if you have only one character variable to analyse, PROC FREQ is your friend and procedure to use.

**How do I export proc freq to excel?**

The easiest way to do this is to use ODS EXCEL , if you have SAS 9.4. ods excel file=”yourfilename. xlsx”; proc freq data=sashelp. class; tables age; run; proc freq data=sashelp.

## Can you use a CLASS statement in PROC FREQ?

PROC FREQ does not support the CLASS statement, but that does not mean that does not mean that it does not use classification variables. In a PROC FREQ step the classification variables are implied by usage in the TABLE statement.

## What is ODS output in SAS?

Produces a SAS data set from an output object and manages the selection and exclusion lists for the OUTPUT destination.

**What is the difference between PROC FREQ and PROC means?**

**What is the nlevels option in PROC FREQ?**

If you specify the NLEVELS option in the PROC FREQ statement, PROC FREQ displays the “Number of Variable Levels” table. This table provides the number of levels for all variables named in the TABLES statements.

### How do I determine the number of levels in PROC FREQ?

If you specify the NLEVELS option in the PROC FREQ statement, PROC FREQ displays the “Number of Variable Levels” table. This table provides the number of levels for all variables named in the TABLES statements. PROC FREQ determines the variable levels from the formatted variable values.

### What type of variables are used in PROC FREQ?

These variables can be either character or numeric, but the procedure treats them as categorical variables. PROC FREQ uses the formatted values of the TABLES variable to determine the categorical variable levels.

**How to use PROC FREQ in SAS?**

The basic syntax of the FREQ procedure is: In the first line, PROC FREQ tells SAS to execute the FREQ procedure on the dataset given in the DATA= argument. If desired, additional options you can include on this line are: Adds a table to the output summarizing the number of levels (categories) for each variable named in the TABLES statement.
