Part 1/3: Wilcoxon Signed Rank Test (General Procedure)

[arvindravee]

Greetings Dr. Thamk you for the explanation on the Wilcoxon Signed Rank Test. Here is what I have summarized from the explanation given by Dr. The video basically discusses the general procedure for the Wilcoxon Signed Rank Test, which is a non-parametric statistical test used to compare two related samples or repeated measurements on a single sample. The key steps outlined in the video are:

1. State the null and alternative hypotheses.
2. Rank the absolute differences between the paired observations, ignoring the signs.
3. Assign the ranks to the positive and negative differences.
4. Calculate the test statistic, which is the smaller of the sums of the positive and negative ranks.
5. Compare the test statistic to the critical value from a Wilcoxon signed-rank distribution table to determine statistical significance and make a decision about the null hypothesis.

Salam sejahtera Dr. I am Sharon (D097103) from class group C. Your general explanation for Wilcoxon Signed-Rank Test is clear and understandable. I saw the relationship and differences between both one-sample sign test (much simpler) and wilcoxon signed-rank test (more powerful). Thank you
