One of my students faces this problem in SPSS 26.0: When he runs Kruskal-Wallis test, the Output does not offer him access to the Model Viewer (where the pairwise comparison etc. would be available). I attach the screenshot. Is anybody familiar with this problem?
Solved. The student called the test through the "Legacy dialogue" instead of the new way (which I showed them). Should have figured it out straight away since I was doing the same mistake for a long time...
Good afternoon, may I know the "new way" to run the nonparametric tests that isn't using the "Legacy Dialogue" menu option? I'm having the same issue you described above and I guess you may have the answer on how I can do this correctly.
Gianna De Keles You need to go Analyze - Nonparametric Tests - Independent Samples... There go to Fields tab, popular Test Fields and Groups. If you have more than two groups, SPSS will choose Kruskal-Wallis for you. Double click the result to open the Model Viewer. Works in SPSS 25, 26 and I believe in 27 as well.
So when I go to Analyze, then Nonparametric Tests, the only next menu drop-down option is Legacy Dialogs, then that drops down to offer me "Chi-Square, Binomial, Runs, 1-Sample K-S, 2 Independent Samples, K Independent Samples, 2 Related Samples, K Related Samples". When I choose one of these to run, I don't get a window with a "Fields" tab. For example, when I select "K Independent Samples", I can drag the variables into "Test Variable List" and "Grouping Variable", I can select either Kruskal-Wallis H, Jonckheere-Terpstra, or Median as a Test Type, then I have a button for "Exact" and a button for "Options". The Options allows me to choose Descriptive and Quartile Statistics, and adjust how to handle Missing Values.
I can run the test, I get a table. But the table it outputs is not interactive. Double-clicking it doesn't produce any action and I do not see anywhere to run pairwise comparisons (which is another step I'm supposed to take for my homework).
Gianna De Keles You need to choose the second item in Nonparametric Tests = K independent samples. Not the last one = Legacy Dialogs. Alternatively, you can use this syntax, in which Q2 is the cardinal variable and Q3 the categorical variable:
NPTESTS
/INDEPENDENT TEST (Q2) GROUP (Q3)
/MISSING SCOPE=ANALYSIS USERMISSING=EXCLUDE
/CRITERIA ALPHA=0.05 CILEVEL=95.
Legacy Dialogs is the only option when I select Nonparametric tests, from there I can select the "K Independent Samples". There's no way to not select Legacy Dialogs after Nonparametric tests because it's the only menu option. It sounds like maybe there's something wrong with my SPSS menu then since you are assuming that Legacy Dialogs is somehow part of a longer list of options and on mine it is the only option.
Gianna De Keles Try to run the syntax. It is weird to have only legacy dialogs. By definition it means outdated, obsolete, not to be used anymore... I would check with others from your institution what their SPSS offer and perhaps reinstall.
Oh interesting, thank you for the insight. I haven't learned how to use syntax yet, but I've dabbled in HTML so maybe I can figure that out. Thank you!
