The Outlier Detection Tool is a Microsoft Excel-based function designed to identify and analyse statistical outliers in numerical datasets. The tool implements three established statistical methods for outlier detection: Interquartile Range (IQR), Z-Score analysis, and Percentile-based filtering. The application serves organizations requiring systematic identification of anomalous data points that may indicate measurement errors, data entry mistakes, or genuine extreme values requiring special consideration.
