The computational procedures for the nonparametric procedures discussed in the text will be the same regardless of whether scores are ranked from low to high or from high to low.

Question

Quizplus · Accepted Answer

This statement is true. The nonparametric procedures, such as the Wilcoxon signed-rank test or the Mann-Whitney U test, rely on the rank order of the scores rather than their actual values. Thus, the order of ranking (i.e., from low to high or from high to low) will not affect the results or the computational procedures.
