ANOVA (Analysis of Variance)
What It Is Used For
To analyze the impact on the output of predetermined changes in
the levels of process or product variables.
When to Use It
To help determine whether the variables being experimented on have
a statistically significant impact on the process output.
Important Notes
Although ANOVA calculations can be done by hand with a calculator,
they are much easier to handle and less prone to mistakes if a
computer (software program) is used.
