I have tried to look at the workbook and data to solve this question, but I am having trouble making sense of the data from looking at the workbook and CSV.
Can you give some more explanation about where the various data come from and how they are related? for example, are the tea categories actually in the underlying data, or have they been aliased from some of those abbreviations of numbers and letters? Are the tea categories in the same column with the other questions? What is a "Psid"?
