R Tutorial: Comparing two related groups (paired sample t-test/Wilcoxon test)

[@srishtitripathi8543]

Hello Dr. Paul, I wanted to express my gratitude for your informative video. I have a question about using wilcox.test results for calculating the z score. Does specifying 'alternative = less, greater' make a significant difference in the accuracy of the z-score calculation? I noticed that when I included it, the z-score result changed. What's your advice on this?
