https://developer.ibm.com/answers/questions/503953/post-hoc-test-for-unequal-variances.html
When I try to do a post-hoc comparison for a two-way ANOVA, I can only click on options when equal variances are assumed. I am unable to click on any of the 4 options for unequal variances.
I donĀ“t understand why and what to do about it.

In spss version 25, when I performed Kruskal Wallis test to find the significance of distribution of 5 variables across categories of sites(5 sites), it rejected the null hypothesis in 2 tests. It performed pairwise comparison by default. which test they are performing in this pairwise comparison? Is it a post hoc test or further do I need to perform post hoc?statisticsmissingpairwise-comparisonskruska-wallis_post-hocMon, 18 Mar 2019 04:51:47 GMTatomIIGrouping post hoc significative differences with capital letters (A, AB, B..)
https://developer.ibm.com/answers/questions/490605/grouping-post-hoc-significative-differences-with-c.html
Dear all,
I am unsuccessfully trying to summarize the information I obtained with a Sidak post hoc test. It is clear to me how to check where the significative differences are (sig. < 0.05), but I would like to summarize them with capital letters, to highlight only the significative different means in a bar chart. I have 2 factors and 13 levels, thus I cannot self-select and write in a table the result.

https://developer.ibm.com/answers/questions/488993/unable-to-run-pairwise-post-hoc-analysis-after-kru.html
Hi all,
I have carried out a Kruskal Wallis test that indicated that there is a difference between 4 groups for their depression score.
I have then tried to do a post-hoc analysis to see which groups are different through ( Analyze > Nonparametric tests > Independent samples). In the decision column, it showed unable to compute?

I am confused as to why I was able to carry out the Kruskal Wallis test but unable to run the post-hoc analysis?
Kind regards, Katrina

https://developer.ibm.com/answers/questions/469242/complete-interpretation-of-pairwise-comparison-gra.html
I am seeking advice on the correct interpretation of the pairwise comparison graphic generated by the model viewer when running Dunn's test (SPSS version 23). The yellow lines obviously relate to significance between projects, but what do the black lines between projects mean, and what do the isolated projects mean (the ones represented in the graphic but with no lines connected them to any other project)? Any help much appreciated! Thanks, Nina

https://developer.ibm.com/answers/questions/468190/missing-pairwise-comparison-in-model-viewer-after.html
Hi all,
I'd appreciate some help here, at home I'm using 32bit SPSS version 21.0.0.2 and I'm trying to check the pairwise post hoc comparisons I've carried out following a KW test. I've done exactly the same thing on my uni pc (admittedly it's SPSS version 23), but at home I noticed the expected "Pairwise Comparison" option by the View drop down menu is totally missing (screenshot as attached).
I've mixed between running the syntax:
NPTESTS
/INDEPENDENT TEST (PelvicObliquity PelvicRotation HipFlexion HipAdduction KneeAdduction AnkleAdduction) GROUP (Group)
KRUSKAL_WALLIS(COMPARE=PAIRWISE)
/MISSING SCOPE=ANALYSIS USERMISSING=EXCLUDE
/CRITERIA ALPHA=0.05 CILEVEL=95.
and running the test manually from Analyze > Nonparametric tests > Independent samples etc, I've also implemented the Fix Pack 2, and set the locale to en_UK (or even just english), and lastly tried showing the Output Display as Pivot tables and charts - all of which result in the below. I'm all out of Googling it appears, so if anyone has experienced the same I'd be super thankful to hear the solution!

I can't read the table for the pairwise comparisons in the model viewer after doing a Kruskal-Wallis test. This happens when I am testing several groups, which is 9 in this case. Any suggestions on how to fix this? Attached is the screenshot of the problem.

https://developer.ibm.com/answers/questions/423496/producing-pairwise-comparison-for-a-three-way-repe.html
Hi
I have completed my three way repeated measures ANOVA (2 x 4 x 3) and have found statistically significant 2-way and 3-way interactions. I have the pairwise comparison with the Bonferroni adjustment for the simple main effects but not for the 2-way and 3-way interactions. How do I calculate the pairwise comparison for these interaction effects on SPSS. Also how can I calculate the power and effect sizes for an ANOVA?

I am having trouble entering variable values when conducting a pairwise comparison.
At the Data Editor Screen I select, Analyze; Nonparametric Statistics; Legacy;K-Independent Samples
Then I add the Dependent Variable to the Test Variable Box, and the Independent Variable to the Grouping Variable Box.
When I select OK, I receive an error stating, "Continuous fields cannot be placed in the list."

https://developer.ibm.com/answers/questions/403239/what-is-the-nptests-median-test-pairwise-compariso.html
I am comparing 3 groups in my median test using the NPTESTS command. I cannot find any information about the procedure that then generates the pairwise comparisons you can see within the model viewer. Is the test statistic displayed in the pairwise comparisons section a chi-square? If not, what are they and what are the tests called that are being run there? Can anyone tell me or point me to information about how these pairwise posthoc comparisons are actually being run mathematically? For example, are they using the global median for all 3 groups or are they only using the median for the two groups in the analysis? It's also really important that I know what correction is being used for the adj. sig. column so I can accurately report that?
I've been digging around the internet and IBM site for a couple of hours at this point and have found almost nothing about these pairwise data, probably because almost every median test example I've found is using only 2 samples.

https://developer.ibm.com/answers/questions/364244/problem-with-non-parametric-one-sample-test.html
Hello,
I hope someone can help me out. I am not able to run a one-sample wilcoxon test on SPSS 23. When I click on 'non-parametric tests' the only option I can see is 'legacy dialogues'. A 'one sample' test option does not come up. Therefore, I'm unable to run the wilcoxon test. I've seen that a few other people have had this problem and I did what answers to their questions suggested. I tried re-installing spss 23, I downloaded 23 FP3 Fixpath and even tried deleting the 'com.ibm.spss.plist' from 'Library' --> 'preferences' but nothing is helping.

https://developer.ibm.com/answers/questions/297316/manual-or-automated-pairwise-comparisons.html
Please could someone tell me whether it is better to carry out automated pairwise comparisons or to do them manually, when using repeated measures, non-parametric data?
I originally carried out a Friedman test, followed by (manual) Wilcoxon Signed Rank pairwise pos-hoc tests, applying a Bonferroni correction to adjust the alpha level.
However, it has been pointed out to me that SPSS 23 and 24 can automatically do pairwise comparisons, following a Friedman test.
Therefore, I would like to know which is better/more robust? The automatic comparisons must have been installed on the latest versions of SPSS for a reason, so I would like to know which I should be using.statistics2423automation testingpairwise-comparisonsTue, 23 Aug 2016 09:07:09 GMTFranLSHayeswhy are there two ways of conducting non-parametric repeated measures tests?

Analyze > nonparatmetric tests > legacy dialogs > K related samples
This method will not let you run the automated pairwise comparisons.

I am trying to carry out automated pairwise comparisons (non-parametric). The model viewer table is so small that I cannot read the data however, because it is a model view table I am unable to edit it. Surely there is a way around this? Surely SPSS hasn't got a flaw to the point where you cannot physically read the output.

https://developer.ibm.com/answers/questions/294152/what-are-the-criteria-for-computing-the-pairwise-o.html
Hello,
I know that the pairwise comparison is more conservative than the stepwise comparison, but are there any other criteria to decide which post-hoc test to use? Does anybody know which method or test SPSS uses for the stepwise step-down comparison? And is there a way to calculate p-values for the significant differences in the stepwise comparison as SPSS doesn't provide them?
