Standardization or z-score normalization is a scaling technique where the values are centered around the _____ with a unit _____.
- mean; standard deviation
- mean; variance
- median; interquartile range
- mode; range
Standardization or z-score normalization is a scaling technique where the values are centered around the mean with a unit standard deviation. This technique subtracts the mean from each observation and then divides by the standard deviation, effectively scaling the data to have a mean of 0 and a standard deviation of 1.
