Hello guys,
i googled so much but i can't find an answer to my question. I hope you can help me out. I have the following problem:
In a user study the same participants had to use two different user interfaces for entering their preferences. Both interfaces were designed from scratch. There was no baseline or similar. After the participants used each of the UIs they had to rate some 5-point-likert statements (e.g., This interface is attractive, or This interface seems more suitable), where the worst possible feedback was "strongly disagree" and the best possible feedback was "strongly agree".
Now i want to compare the statements (This interface is attractive) for both interfaces and see if there is a statistically significant difference.
Which test can i use? Can i use the Mann-Whitney-Test to see if there is a difference? Or the fisher's exact test?
Thank you so much!
