Example of Factorial Experiment
A typical factorial experiment is one which measures the yield of a chemical process.
Let factor $A$ be three different temperatures: $100 \cels$, $150 \cels$ and $180 \cels$.
Let factor $B$ be two different pressures: $1$ and $2$ standard atmospheres.
If:
- the yield were to increase as temperature increases at the lower pressure
but:
- the yield were to decrease as temperature increases at the higher pressure
then the factors $A$ and $B$ interact.
