In questionnaires, it is very common to see the questionnaire asking you “From 1 to 5, how much would you rate…?” (1 is totally negative and 5 is totally positive or vice versa).
It is very standard for the marketing research survey design. This kind of question is called ‘Likert Scale’ which could be 5-point, 7-point or 9-point scale. It should be odd-number scale as we want to have ‘neutral’ at the middle.
Generally, we could report this in different way such as
1) Average score – Show overall score for comparison but it could be bias (neutral could be same as extreme negative + extremer positive)
2) Top box – Show how much the absolute positive
3) Top 2 boxes / bottom 2 boxes – Show total positive / negative
There is another method we could visualize this which is called ‘Divergent Bar Chart’ which shows positive and negative score as well as neutral
