Dear #FridayNightListeners, #Rating scales are ubiquitous - be it in product or company evaluations, #employee appraisals or customer satisfaction #surveys. The choice of scale influences the quality of the #data and the #interpretation of the results. There are two main questions that need to be answered, when you want to create such a survey/poll... 1) How many characteristics should there be? 2) Is the number of expressions even or odd? The choice depends on the specific objective and preferences - but the most widespread is probably the 5-point scale, often visualized with stars, e.g. with the values: - "Agree completely", - "Agree somewhat", - "Neither disagree nor agree", - "Disagree somewhat" and - "Disagree completely" or: - "Very good", - "Good", - "Average", - "Poor" and - "Very poor". But why did the scale with 5 options prevail and not 3 or 7? And why odd? Firstly, it is probably the #simplicity: the scale is easy to understand and does not require complex decisions, so it is also quick to fill in, which reduces the burden on respondents. And many people have been familiar with it for a long time (e.g. hotel category). However, the scale only offers limited gradations, which can mask subtle differences. An extension to 7 expands the possibilities, more nuanced ratings and detailed feedback is possible. This can be particularly interesting for more complex topics and several items, e.g. in the context of a #Likert scale. However: It requires more effort and the added value can be low, especially with large samples. The question always arises as to whether an even or odd number of values should be selected. The biggest advantage of scales with an even number, e.g. 4 or 6, is certainly that it "forces" the respondent to take a clear position, which can lead to a tendency in the end, which may, however, be distorted. With an odd number, the middle scale point can serve as an escape category and allows neutral answers if there is uncertainty, which in turn simultaneously - and undesirably - promotes indecision. Incidentally, the Net Promoter Score (#NPS), a key figure in the area of #customerexperience and the likelihood of #recommendations, is a completely different type. The answer is given on a scale from 0 to 10. To calculate the NPS, the percentage of customers who answer the question with 6 or less is subtracted from the percentage of customers who answer with 9 or 10. Here in particular you notice even more than with the 5-star scales - only the high numbers provide sunshine, otherwise it sometimes rains... in any case: it's always based on the past... #RainOrShine by the British pop group #FiveStar was released in 1986. The band consisted of Pearson siblings. In the lyrics, the protagonist describes his romantic partner as a hero who protects them from sorrow and difficulties - come rain or shine.
