Factorial Experiment/Examples/Chemical Process

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.
