Lesson 5: Introduction to Factorial Designs

Printer-friendly versionPrinter-friendly version

Introduction

Factorial designs are the basis for another important principle besides blocking - examining several factors simultaneously.  We will start by looking at just two factors and then generalize to more than two factors. Investigating multiple factors in the same design automatically gives us replication for each of the factors.

Learning objectives & outcomes

Goals for this lesson includes the following

  • Introductory understanding of Factorial Designs as among the most common experimental designs
  • Two factor Factorial Design and its extension to the General Factorial Designs
  • Sample size determination in Factorial Designs
