For a half fraction of a two-level factorial design the maximum resolution possible is equal to the number of factors. 

The random factors in an experiment are assumed to be normally and independently distributed. 

Center points can be used to determine: I. an estimate of pure errorII. an estimate of the sum of the quadratic effectsIII. if a process is running “as usual” 

The above stem and leaf diagram was constructed from a time series. What type of behavior does this time series exhibit?  

The restricted version of the mixed model is a slightly more general model than the unrestricted model because it allows correlation between interaction effects. 

In a random effects experiment the F-statistics for hypothesis testing are identical to those for the fixed effects situation. 

In a nested experiment, the nested factor is always a random effect. 

Part III – Identification

A resolution R design will project into a full factorial in any R of the original factors.
