IASSC Certified Lean Six Sigma Black Belt (ICBB) — Question 74

How many experimental runs exist in a Full Factorial and fully randomized design for 5 factors with 2 replicates for the Corner Points and no Center Points? The factors in the experiment are only at 2-levels.

Answer options

• A. 10
• B. 128
• C. 256
• D. 64

Correct answer: D

Explanation

In a Full Factorial design with 5 factors at 2 levels, the total number of combinations is 2^5, which equals 32. Since there are 2 replicates, the total experimental runs become 32 * 2 = 64. The other options are incorrect as they do not reflect the correct calculation based on the number of factors and replicates.
