I am a teacher, and doing an action research on my students. I want to see if there is a correlation between a newly introduced teaching methodogy and student engagement/interest through use of questionnaires.
There is 3 data sets. First is to measure their PREFERRED teaching environment, second is what the ACTUAL teaching environment is (Pre- new teaching methodology), and the third is the ACTUAL teaching environment (but this time, post-new teaching methodology). There is 15 students. Each number corresponds to the same student (Student 1 in data set 1 is the same as student 1 in dataset 2 and 3).
To see their Preferred teaching environment, the Current teaching environment (Pre teaching intervention and Post teaching intervention).
Questionnaire is rather straightforward, will share. It is 3 sets of same 30 questions. This dataset will only have 15 students who rank their answers from 1-4 (Strongly agree, agree, disagree, strongly disagree)
I want to do a simple analysis of the data (median, mode, correlation) but most importantly I want to visualize the information. Ideally I would like a way to visualize the change in opinion as a whole from one data set to another.
Examples of graph/chart that I feel would be good are divergent stacked bar chart and perhaps a way to show change in opinion.

I am looking at a budget of around 50 USD. Am flexible if the quality can be proven.
