Description
In QuickCheck and PropEr, you can add functions to a property which collect statistical data about the generated data or add labels for classification of generated data. These information are printed on the screen after executing a property. They help to asses the quality of the generator and are useful to analyse whether relevant test cases/branches are executed with the generated data.
At least in PropEr, this is a feature requiring support of the property execution function since the results of a property could contain the statistical data. To calculate the statistics the result of a property must be fed into accumulation functions. The accumulator is printed after executing the property.

Research direction
No files or tests are named. Start by locating the property execution function and reading how property results are handled; determine where generated-data statistics and labels can be accumulated. Done means collected statistics are printed after property execution, with coverage of the relevant result paths.
