D) orthogonal arrays

Question

Quizplus · Accepted Answer

Orthogonal arrays are a special class of fractional designs that enable the efficient estimation of all main effects in conjoint analysis. They help reduce the number of attribute combinations that need to be tested, which makes the analysis more efficient and cost-effective. Part-worth functions, relative importance weights, and attribute levels are all important components of conjoint analysis, but they do not specifically relate to the use of orthogonal arrays.
