| | | | | In this article I provide much more extensive simulations showing the near perfect agreement between the odds ratio (OR) from a proportional odds (PO) model, and the Wilcoxon two-sample test statistic. The agreement is studied by degree of violation of the PO assumption and by the sample size. A refinement in the conversion formula between the OR and the Wilcoxon statistic scaled to 0-1 (corcordance probability) is provided. | |

| | | | | [AI summary] The text discusses statistical concepts and applications, focusing on the Central Limit Theorem (CLT), standard error, and hypothesis testing. It provides examples and solutions for calculating probabilities, percentiles, and z-scores for sample means. The content covers various scenarios, including income distribution, teacher salaries, car occupancy, and bison weights, demonstrating how to use statistical tools like the normalcdf and invNorm functions on a TI-84 calculator. The material emphasizes the importance of understanding sampling distributions and how they relate to population parameters. | |
