Questions §

1. Is the Move Method refactoring generally applied to classes with a higher number of methods than other classes (methods are denoted by the Weighted Methods per Class (WMC) metric)? §

Examining the move_method row in both datasets:

• Xerces has a move_method count of 1053 with a sum of WMC of 122662, which suggests it is often applied to classes with a moderate number of methods.
• Ant has a move_method count of 27, with a sum of WMC of 1375, indicating that it’s generally applied to classes with a lower number of methods.

Therefore, in Xerces, move_method is applied to classes with a moderate number of methods, whereas in Ant, it is applied to classes with a lower number of methods.
