    Reporting Fisher's exact test (chi squared test)

    Hello, I have conducted some chi squared tests but because the assumption for "minimum expected cell frequency" was violated, I'm using the value for Fisher's exact. However, I don't know how I can report the output. For example, the normal chi squared would be reported like this: χ2 (1...

    Wilcoxon rank-sum test report results when Mdns are the same

    I understand that Medians should be reported when writing results of Wilcoxon rank-sum test. For example: "For alcohol users depression levels were significantly lower on Wednesday (Mdn = 7.50) than on Sunday (Mdn = 16.0), p = .012, r = −.45." But suppose that p=.012 but Mdn=7.50 on Wednesday...

    Different degrees of freedom when reporting multiple T-tests

    Please refer to Table attached. This study compares those without a phobic disorder (n=83) with those with a phobic disorder (n=16) on Temperament scores. What I am confused about, is the reporting of the degrees of freedom: shouldn't the degrees of freedom all be the same number (i.e., n -...

    chi-square test of independence sig but all post-hoc not--how to report?

    I am conducting chi-square tests of independence and for any that are significant I am conducting Bonferroni adjusted post-hoc tests. I have a couple of cases where the original test is significant but none of the post-hoc tests are significant. What is the correct way to report this?

    To report or not to report posthocs for a 'back up' test

    Short version - I have run some non-parametric tests (Friedman) as sort of backup to a ANOVA because of an assumption violation - should I report the pairwise comparisons for these tests in addition to planned comparisons I did following the ANOVA? TIA, E...

    Permutation F test - what is the correct F statistic to use?

    Hi all, I'm currently using an ANOVA to analyse some data sets, recently it occurred to me that the data may not be normally distributed - at all. So I decided to 'upgrade' to using a permutation F test which is apparently much more robust in the face of not-normally distributed data. The...

The problem is, I have no idea how to report this in my write-up. I have looked on the internet again, and...

    Reporting Beta + unstandardized CIs?

    Hello, I did a multiple regression analysis and for now always only reported the standardized effect sized (Beta). Since I heard that it would be good practice to also include the CIs, I wonder how this is done in practice - should I just present the standardized effect size next to the...
