# Experimental Design (agent skill)

> Experimental Design is an agent skill (a SKILL.md file) from K-Dense-AI/scientific-agent-skills. Designs experiments and studies BEFORE data is collected — choosing a design, randomizing, blocking, and laying out treatment combinations so results are interpretable. It works with Claude Code, Codex, Cursor, Gemini CLI and GitHub Copilot and has 47,813 GitHub stars across a repository of 7 listed skills.

Designs experiments and studies BEFORE data is collected — choosing a design, randomizing, blocking, and laying out treatment combinations so results are interpretable. Use whenever someone is planning a study, asks how to assign subjects/samples to groups, mentions randomization, blocking, stratification, controls, factorial or fractional-factorial designs, design of experiments (DOE), screening many factors, response-surface optimization, crossover or repeated-measures or split-plot designs,…

## When it triggers

- Trigger even for informal phrasings like "how should I set up this experiment", "how do I avoid confounding", "what's the best way to test these 6 factors", or "assign these mice to conditions".
- use statistical-power; for analyzing data already collected, use statistical-analysis.
- "how should I set up this experiment"
- "how do I avoid confounding"
- "what's the best way to test these 6 factors"
- "assign these mice to conditions"

## Add this skill
