Category:Factorial Experiments

This category contains results about Factorial Experiments.
Definitions specific to this category can be found in Definitions/Factorial Experiments.

A factorial experiment is an experiment structured so that several different types of treatment can be compared, at different qualitative or quantitative levels.

The design will allow the experimenter to see whether the effects of each factor is additive, or whether they interact.

Results are typically analysed by partitioning the between-treatments sum of squares in an ANOVA exercise into:

main effects

and:

interactions.

Designs may involve any number of factors and any number of levels of each factor.

In a randomized block design, every factor-level combination appears once in each block.
