Would you use spearman rank or pearson r for data relating to food and drink expenditures?
spearman rank would seem to be the better from what i can tell, as that is to compare 2 sets of data (in your case food and drink as separate sets of data) where as pearson rank would ask you to number each item depending on it’s value and this would mean you would need to combine the food and drink into a single set of data making it harder to do a side by side comparison
