proc-means-proc-univariate-continuous

What problem does it solve?

This Skill addresses the need for descriptive statistics and distribution analysis of continuous variables in SAS, ensuring data quality and normality checks before applying parametric tests.

Core Features & Use Cases

• Summary Statistics: Generate statistics like mean, median, standard deviation, minimum, and maximum.
• Distribution Analysis: Assess the shape and normality of distributions with histograms, Q-Q plots, and normality tests.
• Stratified Summaries: Obtain summary statistics for continuous variables stratified by categorical variables.
• Use Case: Before running a t-test or linear regression, use this Skill to check if the data follows a normal distribution.

Quick Start

Run PROC MEANS and PROC UNIVARIATE on the dataset 'mydata' for the variable 'systolic_bp'.
