“An extreme values that stand out greatly from overall pattern of values”

It is interesting to see the translations of “outlier” — according to its context — in English:

  • Atypical
  • Featured
  • Exceptional
  • Abnormal

According to Wikipedia, the outliers in our dataset will be the values that “escape the range where most samples are concentrated” or the samples that are distant from other observations
