How do non-parametric statistical methods deal with outliers compared to parametric methods?

  • They are more robust to outliers
  • They are more sensitive to outliers
  • They don't handle outliers
  • They eliminate outliers before analysis
Non-parametric statistical methods are more robust to outliers compared to parametric methods. This is because non-parametric tests often use medians and ranks, which are less sensitive to extreme values, compared to means which are used in parametric tests.
