Document Summary

Identity: objects that are different receive different scores. Magnitude: ordering of numbers represents ordering of the variable- numbers are assigned in order so that some numbers represent more or less of the variable. Equal unit size: a difference of 1 is the same amount throughout the entire scale. Absolute zero: a value of zero represents the absence of the variable being measured. Objects or individuals are assigned to categories with no numerical properties. Variables on this scale are called categorical variables. Can be assigned numbers, but do not carry any numerical weight. The categories form a rank order along a continuum. Ordinal data is referred to as ranked data. Ranking score does not necessarily have equal unit size. Units of measurement (intervals) between the numbers on the scale are equal in size. Meets criteria of identity, magnitude and equal unit size, but not absolute zero.
