Can I use this for clinical trial data?

Absolutely, the skill includes support for Odds Ratios (OR) and Risk Ratios (RR), which are standard for binary outcomes in clinical and medical research.

Does this skill support ANOVA results?

Yes, it can calculate Eta-squared and Partial Eta-squared to explain the proportion of variance associated with different effects in an ANOVA.

What is the Effect Size skill for Claude Code?

It is a specialized capability that allows Claude to calculate and interpret standardized metrics like Cohen’s d and Eta-squared to measure the magnitude of research findings.

When should I use effect sizes instead of p-values?

While p-values indicate if an effect exists, effect sizes show how large that effect is, which is crucial for determining practical significance in research and data science.

Does it provide confidence intervals?

Yes, the skill emphasizes reporting best estimates alongside 95% confidence intervals to demonstrate the precision of the effect size estimate.

Calculates and interprets standardized effect sizes to quantify the magnitude of research findings beyond simple p-values.

The Effect Size Calculation skill empowers researchers and data scientists to move beyond statistical significance by quantifying the practical impact of their results. It supports a wide range of standardized metrics, including Cohen’s d for group differences, Pearson’s r for correlations, and Eta-squared for ANOVA, providing necessary context for meta-analyses, grant applications, and study planning. By integrating automated calculations with mandatory confidence interval reporting, this skill ensures that Claude Code produces robust, publication-ready statistical interpretations that meet modern scientific standards.
