How to Handle Outlier Values?

Answer»

An OUTLIER is an observation in the dataset that is far away from other observations in the dataset. Tools used to DISCOVER outliers are

  • Box plot
  • Z-score
  • Scatter plot, etc.

Typically, we need to follow three SIMPLE strategies to handle outliers:

  • We can DROP them. 
  • We can mark them as outliers and include them as a feature. 
  • Likewise, we can TRANSFORM the feature to reduce the effect of the outlier.
