  39.5 + 0.5

  =40, not 41

  55.5 + 0.5

  =56, not 57

  Its only possible if you round up 40.1 to 41, which is also bad math. When there are 3 variables properly rounded up, you can only have 3x0.5 added.

    What I say is that there is more than three variables. The three variables are already the result of addition if other variables rounded.

      So there were other options you mean? Like 0.5% couldn’t read, 0.5% drew a picture of a gun instead of answering, etc?

        0.5% strongly approve, rounds up to 1%. 39.5% somewhat approve, rounds up to 40%. The proportion of people who, to varying degrees, approve is then listed as 41%, because otherwise people would see it as them saying 1+40=40.

        People are going to say they don’t understand math either way, so they just need to pick a convention and stick to it.

    39.5 = 40 0.5 = 1 40 + 1 = 41

    55.5 = 56 0.5 = 1 56 + 1 = 57

    3.5 = 4

    Since the original 5 numbers only add up to 95.5, you have a leftover 0.5 to distribute between them. After doing so, you would have what could have been the original results before rounding.

      Yet this is based on the assumption there were more options, plus the total should still not exceed 100%

  That is doing it wrong. You should only ever round as the last step before display.
