The quality report captures the Synthesis, Coverage and Boundaries. This guide contains some technical details about each property.
Is the synthetic data unique or does it copy the real rows?
This property applies the NewRowSynthesis metric to the data to form the Synthesis score. If there are multiple tables in your dataset, then the Synthesis score is the average for each table.
Does the synthetic data cover the range of possible values?
This property applies metrics based on the column types.
This yields a separate score for every column. The final Coverage score is the average of all columns.
Does the synthetic data respect the boundaries set by the real data?
This method applies the BoundaryAdherence metric to numerical columns only. The final score is the average of all the columns.
