# dataauditnode properties #

![Data Audit node icon](https://dataplatform.cloud.ibm.com/docs/content/wsd/nodes/scripting_guide/clementine/images/dataauditnodeicon.png)The Data Audit node provides a comprehensive first look at the data, including summary statistics, histograms and distribution for each field, as well as information on outliers, missing values, and extremes\. Results are displayed in an easy\-to\-read matrix that can be sorted and used to generate full\-size graphs and data preparation nodes\.
