So I made a questionnaire using Likert Scale. Let's say that I want to know "user's satisfaction of new web interface", where I used 5 questions with Likert Scale to answer that one question. The amount of sample is 40 and the example of the item is like this:
1) I'm comfortable with the new interface. [1 - 2 - 3 - 4 - 5]
scale meaning: [ 1 strongly disagree - - - 5 strongly agree ]
Because I have not much time and my knowledge in Statistics is very low, I thought of using the simple and most basic one to analyze the data. I read here and there, and my understanding is that since Likert is ordinal, don't use mean, use mode and median.
Now what I'm confused is, what those mode and median means? All the source said something about use mode or mean or median of frequency etc, but what is it that they represents?
For example, say the mode of question above is 4, and the median is 3. So what it is that they say? Something like, for mode = 4 : "4 means agree, so most of the user agree it's comfortable". But then how to relate this to other question result? And also, if frequency for 4 is 15 and frequency for 3 is 12, there's a lil difference between them, not sure I can say "most" user agrees...
Is the conclusion something I make myself or is there is there any example/guide on analyze Likert like this? When I couldn't find it, I've tried searching for chi-square and t-test, but not just I don't really understand why one use one, I can't find any example either.
