What is descriptive analysis SAS?
PROC MEANS is one of the most common SAS procedures used for analyzing data. It is used to calculate descriptive statistics like the number of observations (N), mean, standard deviation, and max and min value. This code will compute descriptive statistics for all the numeric variables in the dataset.
What are summary statistics in SAS?
In SAS, you can use the UNIVARIATE , MEANS , or SUMMARY procedures to obtain summary statistics such as the median, skewness, and kurtosis. The UNIVARIATE procedure provides a variety of summary statistics for each variable listed in the VAR statement without special options.
What is categorical variable in SAS?
A categorical variable is a variable that assumes only a limited number of discrete values. The measurement scale for a categorical variable is unrestricted. It can be nominal, which means that the observed levels are not ordered. It can be ordinal, which means that the observed levels are ordered in some way.
What is Proc Freq?
The PROC FREQ is one of the most frequently used SAS procedures which helps to summarize categorical variable. It calculates count/frequency and cumulative frequency of categories of a categorical variable. It also produces bar charts and tests for association between two categorical variables.

ABSTRACT. PROC MEANS is a basic procedure within BASE SAS® used primarily for answering questions about quantities (How much?, What is the average?, What is the total?, etc.) It is the procedure that I use second only to PROC FREQ in both data management and basic data analysis.
What is Maxdec in SAS?

What does Proc Summary do in SAS?
Proc Summary stores descriptive statistics in a data set. Proc Means displays descriptive statistics in output destinations.
What is %let in SAS?
%let creates a macro variable. The value of the macro variable is stored in the macro table. Before the value of the macro variable goes into the symbol table, macro triggers ( & and % are resolved or executed).
What’s the difference between categorical and quantitative?
Categorical variables take category or label values and place an individual into one of several groups. Quantitative variables take numerical values and represent some kind of measurement. In our medical example, age is an example of a quantitative variable because it can take on multiple numerical values.
What does tables do in SAS?
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.
Where is syntax in SAS?
The WHERE statement selects observations in SAS data sets only, whereas the subsetting IF statement selects observations from an existing SAS data set or from observations that are created with an INPUT statement.
What are the different descriptive techniques in SAS?

How to print the most recent data set in SAS?
By default, Proc Print will list values for the most recently created SAS data set. However, to be more specific, you can tell SAS the data set that you wish to have printed by using the data = option in the proc print statement, as shown below. This option is highly recommended.
