Factors that determine suitability of rating system/scale for user satisfaction (for an app)
We want to ask our users whether they are satisfied with our app or not. For this purpose we will display a pop-up upon entering the app with 1 question. how satisfied are you with our app. I'm trying to convince the other stakeholder we should use a 5 scale answer and not a 2. the 2 scale answer will have a thumb up and thumb down will the 5 scale answer will have the star rating.
- which of the 2 is more effective? my opinion is clear about that
- can you give a reference for research/use case in your answer please
Thanks.
according to this the 2 is less preferred. https://conversionxl.com/blog/survey-response-scales/
