Details
In this example of projective mapping with vocabulary,
7 (fictitious) assessors evaluated 7 Beers
First, each assessor positionned the 7 beers on a sheet
of paper according to the perceived similarity between the beers.
For each assessor, the position of the beers is recorded
from the and
coordinates.
Second, the assessors are asked if they can describe the
beers with some freely chosen descriptors. These descriptors
are stored in a list with 7 elements (one per assessor)
where each element of the list
is a 7 component vector (one per beer) where each element stores
the words used to describe a beer
(words are separated with spaces).
The coordinates of the beers on the sheet of paper
are stored in the sheet
Maps
, the Vocabulary generated
by the assessors is stored in the sheet
