statistical-reporting

statistical-reporting is a skill for Claude Code, Codex from aiming-lab/AutoResearchClaw. It costs 29 tokens per session (835 once invoked), scanned A, original, MIT.

A skill for choosing statistical tests, checking whether their assumptions are reasonable, and writing results in APA style. APA is a common format for reporting research findings.

In plain words
What is it for?
Use it to compare groups, test relationships, predict outcomes, check normality and variance assumptions, and draft statistical results sections.
Why use it?
It helps match the analysis to the study design and data, reducing the risk of using an unsuitable test or reporting results incompletely.

About the project

AutoResearchClaw is a system that turns a research idea into a scientific paper through autonomous and collaborative AI research workflows. It is for researchers who want agents to investigate questions, run experiments, and produce papers, with optional human guidance. Catalogue skills and agents provide parts of its research workflow.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

statistical-reporting scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Statistical Reporting Best Practice

Test Selection Quick Reference

  1. Comparing two groups (independent, normal): Independent t-test
  2. Comparing two groups (independent, non-normal): Mann-Whitney U test
  3. Comparing two groups (paired, normal): Paired t-test
  4. Comparing two groups (paired, non-normal): Wilcoxon signed-rank test
  5. Comparing 3+ groups (independent, normal): One-way ANOVA + post-hoc
  6. Comparing 3+ groups (non-normal): Kruskal-Wallis test
  7. Relationship between continuous variables: Pearson or Spearman correlation
  8. Categorical outcomes: Chi-square or Fisher's exact test
  9. Predicting continuous outcome: Linear regression
  10. Predicting binary outcome: Logistic regression

Assumption Checking

  1. Normality: Shapiro-Wilk test (n < 50) or visual Q-Q plots
  2. Homogeneity of variance: Levene's test before t-tests and ANOVA
  3. Independence: Verify study design ensures independent observations
  4. Linearity: Scatter plots and residual plots for regression
  5. Multicollinearity: VIF < 5 for multiple regression predictors
  6. When assumptions are violated, use non-parametric alternatives or robust methods

APA Reporting Format

  1. t-test: t(df) = X.XX, p = .XXX, d = X.XX
  2. ANOVA: F(df_between, df_within) = X.XX, p = .XXX, eta-squared = .XX
  3. Correlation: r(df) = .XX, p = .XXX [95% CI: .XX, .XX]
  4. Chi-square: chi-square(df, N = XXX) = X.XX, p = .XXX
  5. Regression: beta = X.XX, SE = X.XX, t = X.XX, p = .XXX
  6. Always report exact p-values (not "p < .05") unless p < .001
  7. Use leading zero for values that can exceed 1 (e.g., t = 0.50) but not for those bounded by 1 (e.g., p = .032, r = .45)

Effect Sizes

  1. ALWAYS report effect sizes alongside p-values
  2. Cohen's d for group comparisons: small = 0.2, medium = 0.5, large = 0.8
  3. Eta-squared for ANOVA: small = .01, medium = .06, large = .14
  4. R-squared for regression: report adjusted R-squared for multiple predictors
  5. Odds ratios for logistic regression with 95% confidence intervals
  6. Distinguish statistical significance from practical significance

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

statistical-reporting is a skill published in the GitHub repository aiming-lab/AutoResearchClaw (14,335 stars, last pushed 17d ago), licensed MIT. It adds 29 tokens to every session and 835 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
