To convert a dataset in order to perform the Paired Samples Wilcoxon Signed Rank Test, you need to follow these steps:
Calculate the differences between the pairs of observations in the dataset.
Rank the absolute differences obtained in step 1 from smallest to largest, ignoring the signs.
Assign positive or negative signs to each rank according to the sign of the difference in step 1.
Calculate the sum of the ranks with positive signs (R+) and the sum of the ranks with negative signs (R-).
Use the formula W = min(R+, R-) to calculate the test statistic.
Determine the critical value of W from a Wilcoxon signed rank table or use a statistical software to calculate the p-value.
Compare the calculated test statistic to the critical value or compare the p-value to the predetermined significance level to determine if there is a significant difference between the paired samples.
