I’m a novice in statistical analysis of empirical data and I was wondering if you experts could take a look at my project and tell me if I’m missing something and/or help me find the best approach.
I’m interested in how closely people consider two concepts to be connected and which connection they consider the closest.
I would like to ask a large group of people (n > 50) to rate on a 7 point Likert-type how close they consider the connection between, e.g.:
yellow and joy
red and joy
blue and joy
The scale is running from ‘no connection’ =1 to ‘immediate, i.e. extremely close connection’ = 7
My approach is to calculate median and IQR for all responses, e.g.:
yellow and joy -> Median: 5; IQR: 4
red and joy -> Median: 6.5; IQR: 1.25
blue and joy -> Median: 4.5; IQR: 2.25
Thus, I would argue that red and joy are most closely connected and I would use them in further steps of my project.
My first question is: Do I miss something?
That is, do I need to calculate something else? For example, I don’t see how and if I should carry out a test of significance…
My second question is:
My data consists of the age of all respondents and the time they took for each response/rating, too.
Is there a way to relate their rating score, their age and their response time for each item?
