The STANDARD Procedure |
Standardizing values removes the location and scale attributes from a set of data. The formula to compute standardized values is
![]() |
is a new standardized value |
![]() |
is the value of STD= |
![]() |
is the value of MEAN= |
![]() |
is an observation's value |
![]() |
is a variable's mean |
![]() |
is a variable's standard deviation. |
PROC STANDARD calculates the mean (
) and standard deviation (
) from the input data set. The resulting standardized
variable has a mean of M and a standard deviation of S.
If the data are normally distributed, standardizing is also studentizing since the resulting data have a Student's t distribution.
