Can the question categories be combined or not. Do I just build the overall sum of the whole question, or do I have to multiply the likert-values of each cell with a number fitting for that likert scale? SD 0 5 0 2 4 11 Scale or is it still ordinal? What I did was: (4 - 1) * (x - 1) / (5 - 1) + 1 = 3 * (x - 1) / 4 + 1 = (3/4) * x - (3/4) + 1 = (3/4) * x + (1/4) 0
