Reporting results from one sample Wilcoxon signed-rank test in R

// Reporting results from one sample Wilcoxon signed-rank test in R // The one sample Wilcoxon-test in R usually consists of two parts: First, the one sample Wilcoxon test itself, which compares your sample median and a hypothesized median (i.e. population median). Second, in the case of a significant difference - the effect size r. The reporting is limited to the essentials: the z-value, p-value and effect size. The latter is also to be classified, optionally with Cohen (1992): A Power Primer, or the respective research field-specific limits. Please note, that the z-statistics needs to be calculated manually. For this purpose you can refer to Field (2012) Discovering statistics using R, p. 665. No worries though, the video will also briefly dicsuss this. Sample formulation: ================= "The sample AGE (MDN =36) is different from (30) the hypothesized/population median, z = -6.22; p ◀ .001, r = 0.872. The difference is large, according to Cohen (1992)." ⏰ Timestamps: ============== 0:00 Introduction and overview 0:10 Calculation of the z-statistic 0:34 One sample Wilcoxon-test results 0:47 Effect size r If you have any questions or suggestions regarding the write-up for the one sample Wilcoxon-test, please use the comment function.
