This question type is the most convenient way to display questions where different topics have the same possible answers.
This question type allows the respondents to choose one criteria in the head of the column, on the basis of which they then evaluate the items or topics that are located in rows on the left side of the table.
An example of such a question could be satisfaction with a website. For example, the developers of a website can use a single question to gain insight into user satisfaction with the design, usability, speed, etc. To achieve the same effect without this question type, three individual questions of the 'Categories - Single Answer' type would be needed instead, which would complicate the creation of the questionnaire and the subsequent analysis of the data.
