Computing z-Scores Using SPSS

Using the data below:

1. Determine the z-score that corresponds to each teacher’s salary and enter them in the table below. (Follow the steps on the second page).

The following data are from a survey of high school teachers.

SALARY
SEX
ZSALARY

35,000
Male

18,000
Female

20,000
Male

50,000
Female

38,000
Male

20,000
Female

75,000
Male

40,000
Female

30,000
Male

22,000
Female

23,000
Male

45,000
Female

Follow the instructions below. For salary be sure to use “scale” for measure (and you will be entering the actual number so no need for values); sex is a nominal variable (Male= 1, Female=2).

In SPSS, we compute z-scores via the Descriptives command.

After you enter the data above, click Analyze, then Descriptive Statistics, then Descriptives – this will take you to the dialog box for descriptives.

In the bottom-left corner you will see a check box labeled “Save standardized values as variables”, check this box and move the variable SALARY into the right-hand blank. Then click OK to complete the analysis. You will see the standard output from the Descriptives command. Notice that the z-scores are not listed. SPSS inserts them into the data window as a new variable (ZSALARY). Copy and paste your results to this document.

2. Write a brief (but thorough) analysis of what these z-scores say about each teacher’s salary.
