SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires numpy, pandas, scipy, matplotlib, seaborn, typing, and includes scripts (resource) and references (resource) components.

What problem does it solve?

It helps you pick appropriate statistical tests and reliably report results by guiding assumption checks, effect sizes, power analysis, and APA-style write-ups.

Core Features & Use Cases

  • Test selection guidance: Choose tests matched to your variables (group counts, outcome type, and distribution assumptions) for scenarios like t-tests, ANOVA, chi-square, regression, and correlation.
  • Assumption checking workflow: Run systematic diagnostics for normality, homogeneity of variance, outliers, and regression linearity to decide when to switch to non-parametric alternatives or corrections like Welch’s.
  • Professional reporting: Produce publication-ready APA-style reporting elements, including required statistics (test results, effect sizes with interpretation, and diagnostic outcomes).

Quick Start

Use the statistical-analysis skill to determine which test to run for a two-group dataset after checking normality, variance homogeneity, and then generate an APA-ready results summary.

FAQPage Schema
How do I choose the right statistical test and write an APA-style results section?

To choose the right statistical test and write an APA-style results section, you match tests to your variables and distribution, run assumption checks, calculate effect sizes with confidence intervals, and generate a publication-ready summary.

What is the best way to check statistical assumptions like normality and variance homogeneity before running a t-test or ANOVA?

Checking statistical assumptions requires running systematic diagnostics for normality, variance homogeneity, outliers, and linearity to determine if you need corrections like Welch’s or non-parametric alternatives before running a t-test or ANOVA.

How do I calculate effect sizes with confidence intervals for academic research reporting?

You calculate effect sizes with confidence intervals for academic research reporting by applying the selected statistical test, extracting the magnitude metrics, and formatting them into an APA-compliant diagnostic interpretation with remediation recommendations.

Can I use Python with pandas and scipy for power analysis and Bayesian statistics alternatives?

Yes, you can use Python with pandas and scipy for power analysis and Bayesian statistics alternatives to plan study sampling and generate diagnostic interpretations when standard hypothesis testing assumptions are violated.

When should I switch to non-parametric statistical tests instead of standard regression or correlation?

You should switch to non-parametric statistical tests instead of standard regression or correlation when systematic assumption checks fail for normality, variance homogeneity, or regression linearity, triggering remediation recommendations.
