Mann-Whitney U Test Results for Diameter Measurements of Two Independent Samples

5.5 KB of statistical test results in an XLS file, authored by Erika Z. Chung and last updated on 2026-05-27. The dataset contains the output of a Mann-Whitney U test applied to diameter measurements from two independent samples. This non-parametric test is used to determine if there is a significant difference between the distributions of the two groups.

Use Cases

• Compare median diameter values between two independent groups based on the Mann-Whitney test results.
• Validate non-parametric statistical methods for analyzing diameter data where normality assumptions are violated.
• Use as a teaching example for applying the Mann-Whitney U test to a real-world measurement problem.

Strengths

• Dataset is small (5.5 KB), making it quick to download and inspect.
• Data is shared under a permissive CC-BY-4.0 license, allowing for reuse with attribution.

Limitations

• Row count and column definitions are unknown, which limits suitability assessment.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
