research-hypothesis-testing

research-hypothesis-testing is a skill for Claude Code, Codex from ItamarZand88/awesome-agent-conventions. It costs 0 tokens per session (2,205 once invoked), scanned A, a copy of hypothesis-testing-guide, MIT.

A guide to statistical hypothesis testing: methods for checking whether a difference in data is likely to reflect a real effect rather than random variation. It also covers sample-size planning and how to report results.

In plain words
What is it for?
Use it to select and run tests such as t-tests or ANOVA, check their assumptions, calculate statistical power and sample size, account for multiple comparisons, and report effect sizes.
Why use it?
It helps prevent common mistakes such as choosing the wrong test, ignoring assumptions, confusing practical importance with statistical significance, or finding misleading results by trying many tests.

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

research-hypothesis-testing 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 10d 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.

Origin

Hypothesis Testing Guide

Overview

Hypothesis testing is the backbone of empirical research. It provides a principled framework for deciding whether observed differences in data reflect genuine effects or merely random variation. Misuse of hypothesis tests -- p-hacking, ignoring assumptions, confusing statistical and practical significance -- is a leading cause of irreproducible findings.

This guide covers the core hypothesis testing framework, the most commonly used tests across disciplines, assumption checking, effect size reporting, power analysis for sample size planning, and multiple comparison corrections. Each test is accompanied by Python code using scipy, statsmodels, and pingouin, ready to integrate into research workflows.

The goal is not just to help you run tests, but to help you run the right test correctly and report results following modern standards (APA 7th edition, journal best practices).

The Hypothesis Testing Framework

Step-by-Step Procedure

  1. State hypotheses. Define H0 (null: no effect) and H1 (alternative: effect exists).
  2. Choose significance level. Typically alpha = 0.05, but justify your choice.
  3. Select the appropriate test. Based on data type, distribution, and design.
  4. Check assumptions. Normality, homogeneity of variance, independence.
  5. Compute test statistic and p-value.
  6. Report effect size and confidence interval. p-values alone are insufficient.
  7. Make a decision. Reject or fail to reject H0, with practical interpretation.

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.
