LinkedIn Learning Module SAS Summarizing Data
In SAS® 9.4 Cert Prep: Part 09 Summarizing Data, the module focuses on techniques for aggregating and summarizing datasets using SAS procedures. It covers methods like using the PROC MEANS, PROC SUMMARY, and PROC FREQ to calculate statistical measures such as means, sums, and frequencies. Additionally, it includes options for grouping data, applying formats, and managing missing values.
Key Takeaways:
- PROC MEANS & PROC SUMMARY: These procedures are used to compute descriptive statistics, such as means, medians, and variances, for numeric variables.
- Grouping Data: SAS allows you to group your data using the
CLASSandBYstatements, making it easy to compute statistics across different categories. - PROC FREQ: Useful for counting occurrences of categorical data and can create frequency tables for both single and multiple variables.
- Handling Missing Data: Strategies for summarizing data even when missing values are present, including how to ignore or account for them.
- Output Customization: Summarizing results can be customized for reports or further analysis by exporting output tables and controlling the format of statistics.
