I've conducted a Likert-style survey with $45$ questions in which $15$ people participated. Each question was repeated six times, so I have six answers from every participant for every question. All answers are $\in \{1, 2, 3, 4, 5\}$.
What I'm trying to visualize are the differences in consistency with which the participants answered the six repetitions of each question. For example, participant $a$ gave six answers to question $q_1: [3, 5, 1, 1, 1, 2]$ while participant $b$ gave the following answers to the same question $q_1:[4, 4, 1, 1, 2, 2]$. The order does not matter to me, what I'm interested in is the count ($a$ chose $1$ three times, $2$ one time, $3$ one time and $5$ one time while $b$ chose $1$ two times, $2$ two times and $4$ two times).
My data looks like this:
# participant 1
question, 1_count, 2_count, 3_count, 4_count, 5_count
q_1,1,1,1,0,3
q_2,0,6,0,0,0
q_3,3,0,0,0,3
q_4,1,1,2,2,0
q_5,1,1,0,0,4
# participant 2
question, 1_count, 2_count, 3_count, 4_count, 5_count
q_1,1,5,0,0,0
q_2,1,1,1,1,1
q_3,0,0,3,0,3
q_4,1,1,0,0,4
q_5,2,2,0,2,0
I wasn't able to find a suitable visualization technique. Do you have any suggestions?
facet_grid
in R, like this). (You could also make ridge histograms, though they do not render nicely for this few observations and this many distributions.) $\endgroup$
