Abstract: Split-plot designs and the appropriate statistical analysis of the resulting data are frequently misunderstood by industrial experimenters. The objective of this tutorial paper is to review split-plot designs for full and fractional factorial experiments, explain why they often arise in industrial experiments, and provide several illustrative examples.

Keywords: split-plot design; split-plot factorial experiments; split-plot fractional factorial experiments; ANOVA; random effects; statistical analysis.
