Even so, treating age as categorical rather than, at least, ordinal would ignore the ordered nature of ages. though I have to multiply otherwise the mean would always equal to the overall amount of answers : number of answers: Assuming Q1 is Question 1, each number resembles the amount of people who chose that likert-point as answer: ++ + 0 - -- Mean Q1 2 3 4 6 12 5,4 The means of this would always be soleley dependant on the amount of people who took part.
