1.

How many experimental runs exist in a Full Factorial and fully randomized design for 4 factors with 2 replicates for the Corner Points and no Center Points? The
factors in the experiment are only at 2-levels.

10 32 256 64

2.

If an experiment has 5 factors and no replicates for a 2-level Experimental Design with 16 experimental runs which statement is incorrect?

The Experimental Design is half-fractional The Main Effects are confounded with only 4-way interactions The Main Effects for the 5 factors are not aliased or confounded but the 2-way interactions are confounded with the 3-way interactions The experiment has 8 experimental runs with the first factor at the high level

3.

Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note: There are 2 correct answers).

It is unknown from this graph how many factors were in the Experimental Design The factors to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 2.06 The effects to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 0.05 The factors to keep in the mathematical model with a 5% alpha risk are BE, AB, A and AD

4.

Fractional Factorial, ____________and Response Surface Method are types of planned experiments.

Multi-Vari Analysis Baldridge Channels One Factor at a Time or OFAT Factorial Design

5.

Relative to a Design of Experiments the term ________________ refers to variables being a linear combination of each other.
