Create a Fractional Factorial Design in Python

This guide walks you through creating fractional factorial designs using Python's pyDOE3 package. I won't cover the theory of what fractional designs are or how they work—if you need that background

Example of a Fractional Factorial Design

Introduction Fractional factorial designs are a powerful tool in the Design of Experiments (DoE) toolbox. They allow you to systematically explore the effects of multiple factors while significantl

Introducing Fractional & Central Composite Designs

When it comes to experimental design, full factorial designs are often the starting point. They’re straightforward, systematic, and provide a complete picture of the interactions between factors. Howe

Professional DOE software can cost thousands of dollars - money that students and startups often don't have. Fortunately, Python offers a free alternative! The **[pyDOE3](https://pydoe3.readthedocs.io

A step by step example of a full factorial design

Design of Experiments (DoE) can seem intimidating with its statistical terminology and complex analysis methods. But at its core, DoE is about systematically varying factors to understand their effect

The Basics of Designing Better Experiments

How do you perform experiments? Let’s stick with our previous filtration rate example and say we have two factors: temperature and pressure. You’d like to find their optimum settings to max

Do you like chocolate sauce? That's a weird question to ask on a website about experimental design, isn't it? But imagine a waiter asking you if you'd like chocolate sauce with what you ordered. Yo

Principles of DoE: Randomization, Replication, Blocking

Will you reach the same conclusion twice? When I did my PhD, from time to time I was quite happy about some results. They were exactly what I was hoping for. When I presented them to my supervisor,

Key DoE Terms
