You can efficiently view measure details in SAS Viya by utilizing the "View Measure Details" data task within SAS Visual Analytics. This feature provides quick access to basic statistics for all measures in your report or exploration.
Understanding Measure Details in SAS Visual Analytics
The "View Measure Details" function is a powerful data task embedded within SAS Visual Analytics, a key component of SAS Viya. Its primary purpose is to present users with fundamental statistical insights about all the measures (numerical data items) currently active in their dataset. This task helps in quickly understanding the characteristics and distribution of your data, which is crucial for data validation, exploration, and preparing for analysis.
For more general information on SAS Visual Analytics, you can refer to the SAS Visual Analytics documentation.
Step-by-Step Guide to Viewing Measure Details
Accessing the measure details is a straightforward process within the SAS Visual Analytics interface:
- Navigate to the Data Pane: On the left side of your SAS Visual Analytics interface, locate and click on the Data pane. This pane displays all the data items available in your report or exploration.
- Access Actions: Within the Data pane, you will find an Actions menu or button. Click on it to reveal a list of available data tasks.
- Select View Measure Details: From the dropdown menu that appears, select the View Measure Details option.
Upon selection, a new window or tab will open, displaying a comprehensive overview of basic statistics for every measure in your current data source.
What Information Will You See?
The "View Measure Details" task provides a summary of basic statistics for all measures. While the exact statistics can vary slightly based on the data type and context, you can generally expect to see insights such as:
- Count: The number of non-missing values.
- Missing Values: The number of observations where data is absent.
- Sum: The total sum of all values.
- Average (Mean): The arithmetic average of the values.
- Minimum: The smallest value in the measure.
- Maximum: The largest value in the measure.
- Standard Deviation: A measure of the dispersion of the data points around the mean.
- Median: The middle value of the dataset.
These statistics offer a snapshot of your data's health and distribution, facilitating informed decision-making.
Practical Applications and Benefits
Viewing measure details is a quick way to gain insights and offers several practical benefits for data users:
- Quick Data Quality Check: Instantly identify missing values, extreme outliers (via min/max), or unexpected averages that might indicate data quality issues.
- Initial Data Exploration: Get a preliminary understanding of your data's characteristics before diving into complex visualizations or analyses.
- Understanding Data Distribution: Observe the spread and central tendency of your numerical data, helping you to choose appropriate visualization types.
- Validation of Data Imports: Confirm that your imported data is behaving as expected and that measures have been correctly interpreted by SAS Viya.
