The two types of errors DOE setups are needed to understand are
OPTIONS
- Pure error and Lack of Fit error
- Noise and Reproducibility
- Common and Special Causes
- Causal and Lack of Fit error
ANSWER
Pure error and Lack of Fit error
EXPLANATION
DOE setups and coefficients analysis help one to understand the Pure error and lack of fit error of the model, so THE FIRST OPTION is correct.
