| Kind of design | Experiments | Factors | Runs |
|---|---|---|---|
| Full factorial | 1 | 4 | 8 |
| Fractional factorial or screening | 2 | 7 | 16 |
Factors and runs are the medians of each kind.
Full factorial
Every combination of the factor levels.
Fractional factorial or screening
A planned part of the combinations, to find the factors that matter.
