I have used a Likert scale in my survey, where respondents answer statements in terms of 1=strongly agree to 5=strongly disagree. There are 5 items measuring a single type of 'need gratification' and there are 5 different needs.
After summing the five items for each need gratification, a score is obtained between 5 to 25. These scores have been categorised into four "quartiles": 5-10 is Q1 (first quartile) , 10-15 is Q2 , 15-20 is Q3 and 20-25 is Q4 .
How can I test which of the five needs scales has the largest proportion of responses in the 20 to 25 range (Q4)?
