Checks if single intervals in the graph created using the study data deviate significantly from a theoretical distribution expected from the metadata (solid yellow line). The distribution of a variable is defined in the column DISTRIBUTION in the metadata (e.g., normal), whereas the parameters are derived from the empirical data.
The higher the number of identified intervals deviating from the expected distribution, the lower potentially the data quality.
Note: sample size considerations and the graph should be taken into account in addition to the test results.
