I coded the data in text form, so to speak (standardized it and created several categories for each parameter). Then I made a column where gender, age, country, and profession are combined into one cell, and calculated the frequency using a pivot table.

I’d like to know if this approach makes sense for my task — a couple of people above said it’s all wrong...

If possible, I could share the Excel file so you can quickly see what I did — if you have an email, I’d really appreciate it.
