What is meant by Design of Experiments?
Design of experiments (DOE) is a systematic, efficient method that enables scientists and engineers to study the relationship between multiple input variables (aka factors) and key output variables (aka responses). It is a structured approach for collecting data and making discoveries.
Why do we use fractional factorial design?
The basic purpose of a fractional factorial design is to economically investigate cause-and-effect relationships of significance in a given experimental setting. This does not differ in essence from the purpose of any experimental design.
What does the fraction in fractional factorial DOE refer to?
This is when you might choose to run a fractional factorial also referred to as a screening DOE, which uses only a fraction of the total runs. That fraction can be one-half, one-quarter, one-eighth, and so forth depending on the number of factors or variables. Or, in our example, you could run 64, 32, or 16 runs.
What is the main advantage of a fractional factorial design?
The advantage of fractional factorial designs is that they use a subset (fraction) of the full set of possible design runs to estimate the effects, so they are very efficient designs.

What is the difference between factorial and fractional factorial designs?
Generally, a fractional factorial design looks like a full factorial design for fewer factors, with extra factor columns added (but no extra rows). Using fractional factorial design makes experiments cheaper and faster to run, but can also obfuscate interactions between factors.
What assumptions are we making by using a partial factorial?
Using a fractional factorial involves making a major assumption – that higher order interactions (those between three or more factors) are not significant.

What is alias structure in DOE?
What is alias structure? The alias structure describes the confounding pattern that occurs in a design. Terms that are confounded are also said to be aliased. Aliasing, also known as confounding, occurs in fractional factorial designs because the design does not include all of the combinations of factor levels.
What is a resolution 3 design?
Resolution III designs.
These are designs in which no main effects are aliased with any other main effect, but main effects aliased with two-factor interactions and two-factor interactions may be aliased with each other.
