Description

BeersProjectiveMapping_xlsx: an example of an excel file with Projective Mapping and vocabulary. This excel file can be read by read.df.excel. In this example 7 (fictitious) assessors evaluated 7 Beers.

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 X and Y 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 Vocabulary
