I'm working on a research and stumbled upon a study that evaluated participant scores to a 5-point Likert scale. I'm having trouble trying to interpret those results. I want to evaluate the correlation between the scores from the study with my own data (which is scored between 0 and 1).
My first instict was to simply divide the Likert scores by 5 but some thing seems inherently flawed about this method as I feel I'm missing out on a lot of information through this generalisation. Is there a standard way to doing this?
The study I mention only provides with the scores, participant count and basic criteria that the participants could choose from in the method. https://program.ismir2020.net/poster_1-02.html < here's the link to the study in case you want to take a look at it.
