What is Visual Inspection?
Visual inspection uses charts to identify outliers and anomalies that statistical thresholds might miss. Box plots show the IQR and flag points beyond the whiskers. Scatter plots reveal isolated points far from the main cluster. Histograms expose unusual spikes or gaps. Visual inspection is always a valuable complement to numerical outlier detection.
