Większy fragment (jest to definicja "conjoint analysis"):
The first step in a
typical conjoint analysis is to present consumers with a number of product descriptions and
ask for a ranking of them. Product descriptions, defined via a set of physical attributes, are
often hypothetical, but can also be actual products, produced according to an experimental
design. The advantage of conjoint analysis over MDS analysis is the direct relation to the
manipulable attributes. Since these attributes are chosen in advance, however, they also
constitute the greatest problem of this technique.
