Answer:

- It comes under the category of Technical Quality Attributes.

- It indicates how easy it is to change a module without impacting other modules within the application.

- Formula: Ce / (Ce + Ca)

where

Ca - afferent coupling, or incoming dependencies

Ce - efferent coupling, or outgoing dependencies

-As I approach to 1, the module is more stable and easier to change as only few other modules in the application use them
