Sorting task (or categorization) consists in asking the panelists to gather the products into different groups according to their resemblance.
Once the groups are made, panelists are often asked to describe their groups by words.
The data set used is made of as many rows as there are products and as many columns as there are panelists.
Each cell corresponds either to the number of the group the product belongs to or to the sequence of words used to describe the group the product belongs to.
