Statistical Test Results for µCT-Scanned vs. Unscanned Petrous Bones

Wilcoxon rank-sum test results comparing micro-CT-scanned and unscanned petrous bones across key molecular parameters. The dataset includes results for sample sizes of 50 scanned and 43 non-scanned bones for most parameters, and 13 scanned versus 18 non-scanned for nuclear contamination in XY individuals. It was authored by Lumila Paula Menéndez and last updated on figshare in April 2026.

Use Cases

• Assess the impact of micro-CT scanning on molecular preservation based on the reported test parameters.
• Validate statistical methods for comparing treated and untreated archaeological samples based on the Wilcoxon test results.
• Benchmark sample size requirements for future studies on petrous bone contamination based on the provided n values.
• Replicate or extend null-finding analyses for imaging effects on ancient DNA based on the reported p-values.

Strengths

• Provides explicit sample sizes for each comparison group (e.g., 50 scanned, 43 non-scanned).
• Reports statistical significance levels (p > 0.05) for all tested parameters.
• Dataset is openly licensed under CC-BY-4.0.
• File size is small (5.5 KB), facilitating quick download and inspection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's scope is limited to the specific test results and does not contain the underlying raw measurement data.
