Effect size of the Paired Samples Wilcoxon-test in SPSS

After conducting the paired Wilcoxon signed rank-test in SPSS with the result of a difference between the two measurements, an effect size is needed to quantify/classify the magnitude of this effect. For the paired Wilcoxon-test, r is a suitable effect size. ➡️ Watch next:    • Reporting Paired Samples Wilcoxon-test - r...   Unfortunately, SPSS does not do the calculation for you. Hence, you need to do it manually. r equals the absolute value of the standardized test statistic divided by the number of observations. There is no consensus on what the number of observations is - some authors use the number of paired observations, some use the number of paired observations times 2. Whatever you are deciding to pick, report it. Be aware that the classification is reasearch field specific. For the social and behavioral sciences, the paper Cohen, J. (1992), A Power Primer, p. 157 is usually cited: 📚 Cohen, J. (1992): Quantitative methods in psychology: A power primer. Psychological bulletin, pp. 155-159. ⏰ Timestamps: ============== 0:00 Introduction and prerequisites 0:10 Calculation of r for paired Wilcoxon-test 1:03 Classification of r for the paired Wilcoxon-test If you have any questions or suggestions regarding Effect Size for the paired Wilcoxon-test in SPSS please use the comment function.
