STANDARDIZE(x,m,sd)
- is the value.
- is the mean.
- is the standard deviation.
Description
- This function gives the normalized value of any distribution.
- Standardize is the normalized value for a distribution characterized by a given mean and standard deviation.
- In , is the value to be normalized , is the arithmetic mean of the distribution, and is the standard deviation of the distribution.
- The equation for the normalized value is:
, where is the arithmetic mean and is the standard deviation.
- This function will give the result as error when
1. Any one of the argument is non-numeric. 2. sd<=0
Examples
- =STANDARDIZE(25,20,10.2) = 0.490196078431
