# Standardize

 Standardize[list] shifts and rescales the elements of list to have zero mean and unit sample variance. Standardizeshifts the elements in list by and rescales them to have unit sample variance. Standardizeshifts by and scales by .
• Standardize shifts by a location and rescales by a scale estimated from the elements of list.
• Common choices for and include:
 Mean StandardDeviation zero mean and unit variance Mean shift to mean 0 Median shift by the median StandardDeviation scale to have unit variance
Compute standard scores for data:
Shift to have mean zero without scaling:
Shift by the Median and scale by the InterquartileRange:
Compute standard scores for data:
