SPSS'te Mann Whitney U testi yaparken raporlama da hangi grubun
median'ını alıyoruz? Elimde bir experiment bir control grup var. Hepsini tek data olarak düşünüp mu median'ını raporluyorum?
Mdn=?, U=3.43, p=.038
Mdn=?, U=3.43, p=.038
Example statement of results
In reporting the results of a Mann–Whitney U test, it is important to state:
A measure of the central tendencies of the two groups (means or medians; since the Mann–Whitney U test is an ordinal test, medians are usually recommended)
The value of U (perhaps with some measure of effect size, such as Common language effect size or Rank-biserial correlation).
The sample sizes
The significance level.
In practice some of this information may already have been supplied and common sense should be used in deciding whether to repeat it. A typical report might run,
"Median latencies in groups E and C were 153 and 247 ms; the distributions in the two groups differed significantly (Mann–Whitney U = 10.5, n1 = n2 = 8, P < 0.05 two-tailed)."
