Presence of outliers in the study data are checked using 4 approaches (Tukey, 3SD, Hubert, and SigmaGap). For each value it is indicated how many approaches identifies it as outlier (0 = not an outlier, 4 = an outlier based on 4 approaches).
The higher the number or percentage of identified outliers, the lower potentially the data quality.
