# meansnode properties #

![Means node icon](https://dataplatform.cloud.ibm.com/docs/content/wsd/nodes/scripting_guide/clementine/images/matrixnodeicon.png)The Means node compares the means between independent groups or between pairs of related fields to test whether a significant difference exists\. For example, you could compare mean revenues before and after running a promotion or compare revenues from customers who didn't receive the promotion with those who did\.
