C) Spearman or Kendall tau's correlation coefficient

Question

Quizplus · Accepted Answer

Since the data involves a ratio measurement scale (height in inches) and an ordinal scale (shirt size categorized as small, medium, large), Spearman or Kendall tau's correlation coefficient is appropriate. These non-parametric tests are used to measure the association between variables when at least one of them is not interval or ratio scaled, fitting the scenario described.
