WebFeb 17, 2024 · Using IQR or Boxplot Method to Find Outliers. This method we are evaluating the data into quartiles (25% percentile, 50% percentile and 75% percentile ). We calculate the interquartile range (IQR) and identify the data points that lie outside the range. Here is how calculate the upper and lower data limits WebMar 20, 2024 · That difference is called the IQR (InterQuartile Range). IQR = Q3-Q1 Lower bound = Q1–1.5 (IQR) Upper bound = Q3+1.5 (IQR) Image by author Any values less than the lower bound or greater than the upper bound are outliers.
