Practice by which it is possible, during data processing, to group the answers collected to open questions (the verbatims) by theme in order to quantify them and be able to analyze them via percentages. Very similar answers, although formulated differently by the respondents, are thus grouped together to create a single category. Example: for the open-ended question 'What elements of this product do you dislike? 'the answers “it's too expensive”, “the price is too high”, “it's not cheap”, will be grouped under the title “too expensive” because they all express this same idea.
