To determine outliers, you typically use the interquartile range (IQR), which is calculated from the 25th percentile (Q1) and the 75th percentile (Q3). Outliers are often defined as observations that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR, making knowledge of the 25th percentile essential for their determination.
