WebJan 29, 2024 · In statistics, the upper and lower fences represent the cut-off values for upper and lower outliers in a dataset. They are calculated as: Upper fence = Q3 + (1.5*IQR) Lower fence = Q1 – (1.5*IQR) where IQR stands for “interquartile range” and represents the difference between the 75th percentile and 25th percentile in a dataset.
