1. How do you create a simple experimental design?

1.1 Introduction

A number of experimental design categories have been established to help us, the manufacturers, to diversify our range of quality tools, or to improve and rationalize trials in the field of agronomy, where experimental designs began to emerge thanks to Ronald Fisher, a British statistician and geneticist.

Faced with the multiplicity of experimental designs available, the full factorial design is the most widespread and widely used when the factors are fairly limited (two). For this reason, the remainder of this article will focus on the so-called 2 ² complete factorial design, i.e. a complete factorial design with two factors and two levels per factor.
