My initial plan was to develop the questions using at least one of each of the level of measurement. However, since the way I understand nominal it is more of identifying a classification instead of a measurement, which means I found myself doing most of the questions as nominal. I did the age question as interval, because if I understand the reading interval because the distance between the intervals is the same. I did not do an ordinal because I could not think of a way to come up with an ordered relationship. However, I am confusing myself because according to the reading interval is the same as ordinal except in interval the difference between the values is the same? I am not sure if I have a full understanding...and possibly missing something.
