Click OK.

SPSS runs the descriptives procedure and calculates the z-scores.

Switch over to the Data Editor window.

Figure 15-5 shows the three new standardized variables created at the end of the data file. Note that the screen was split to better illustrate the creation of the new variables. By default, the new variable names are the old variable names prefixed with the letter Z. You can save these variables in the file and use them in any statistical procedure.
