What is the main characteristic of Robust Scaling?
- It is not affected by outliers
- It scales features to a specific range
- It scales the data to unit variance
- It's the most complex scaling technique
Robust scaling uses techniques that are robust to outliers. This method removes the median and scales the data according to the quantile range (Interquartile Range: IQR). The IQR is the range between the 1st quartile (25th percentile) and the 3rd quartile (75th percentile).
