Syntax
STANDARDIZE(x,mean,standard_dev)
X is the value you want to normalize.
Mean is the arithmetic mean of the distribution.
Standard_dev is the standard deviation of the distribution.
Remarks
 If standard_dev ≤ 0, STANDARDIZE returns the #NUM! error value.
 The equation for the normalized value is:
