The STANDARD Procedure |

Standardized Test Scores Using PROC STANDARD shows a simple standardization where the output data set contains standardized student exam scores. The statements that produce the output follow:

proc standard data=score mean=75 std=5 out=stndtest; run; proc print data=stndtest; run;

Z Scores for Each BY Group Using PROC STANDARD shows a more complex example that uses BY-group processing. PROC STANDARD computes Z scores separately for two BY groups by standardizing life-expectancy data to a mean of 0 and a standard deviation of 1. The data are 1950 and 1993 life expectancies at birth for 16 countries. The birth rates for each country, classified as stable or rapid, form the two BY groups. The statements that produce the analysis also

- print statistics for each variable to standardize
- replace missing values with the given
mean
- calculate standardized values using a given mean and standard
deviation
- print the data set with the standardized values.

For an explanation of the program that produces this output, see Standardizing BY Groups and Replacing Missing Values .
