Robust Scaler removes the median and scales the data according to the quantile range (defaults to IQR: Interquartile Range).
The IQR is the range between the 1st quartile (25th quantile) and the 3rd quartile (75th quantile).
Robust scaler should be used when our data has outliers, either in independent or dependent data.
