We recommend you follow along with the examples by downloading and opening employees.sav. SPSS SET TNUMBERS SPSS TNUMBERS determine how data values are displayed. In SPSS, tnumbers (short for […]
One of the most common research questions is do different groups have different mean scores on some variable? This question is best answered in 3 steps: create a table showing mean scores per group -you’ll probably want to include the frequencies and standard deviations as well; create a chart showing mean scores per group; run some statistical test –ANOVA in this case. However, this […]
In some cases, ALTER TYPE in SPSS version 24 seems to report incorrect altered values when converting a string to a numeric value. This results in messed up data while SPSS reports that everything is fine. Let’s try and replicate the problem with the example below. Example We imported some .csv data in which some numeric values were flagged with an “a”. This indicates […]

EXECUTE runs pending transformations but many SPSS users don’t have a clue what that means. More importantly, when should you (not) run EXECUTE? And when do you really need it? Let’s dive in. We’ll use adratings.sav throughout, part of which is shown below. SPSS “Transformations Pending” As you probably figured out, our data hold 18 respondents who rated 3 different advertisements. […]
In SPSS, we sometimes encounter variables that are negatively coded: lower values indicate higher agreement or more positive sentiments. Although this is not really “wrong” in any way, positive coding is more intuitive. Especially when reporting means over variables, most readers naturally expect higher means to indicate something better, not worse. So what’s the best way to reverse code variables? […]
