I build this mosaic plot using R. I would like to know do you interpret each color? What do you mean by standardized ressiduals? Does it already signifies significance also? If not, should I run another significance test by chi-square? Thank you so much.
Using the mosaic plot is part of exploring your data.
It does not assist in analysis.
The standardized residuals are residuals divided by its standard deviation, where the residual is the difference between the data response and the fitted response.
The appreciation of a residual is a key understanding one gains from a basic statistics course - or book.
To work out an analysis plan you need a question to ask?
You have data by month these would NOT be independent. The data may be from a questionnaire- each question may need a separate analysis. Or is the data answers from one question- these aspects of the structure of the data will inform how you analyse the data . What type of data do you have - is it from a multi-level survey? (Villages or regions- are clusters that need to be part of the analysis)
The best thing is to find a local statistician and get some assistance.
