Analyzes observed differences in the process mean at different levels (settings) of an input. To use the one-way ANOVA procedure, you must collect a sample of data at each level of the X-variable.
|When to Use||Purpose|
|Mid-project||Fixing an input at two or more different settings (levels) helps to determine which inputs have significant influence on the mean of the output.|
|Mid-project||Verify that changes to inputs result in significant differences from the pre-project mean.|
Continuous Y, a single X at two or more levels (generally three or more).
