Document Summary
Nominal scale (categorical measures: numbers are just a unique name, not ordered, and any calculations would be meaningless, ex. Jersey numbers, student numbers: qualitative not quantitative. Ordinal scale: numbers (categories) are ordered in sequence of degree but the distances between them don"t mean anything, ex. Satisfaction scale from 1- 5 with 1 being unsatisfied and 5 being. Interval scale [like a ruler with exact intervals (5 cm): numbers (categories) are intervals that are the same exact size. 10 degree interval has same meaning for the difference between 30 and 40 degrees or 80 and 90 degrees: arbitrary zero. Zero is assigned to a location on scale for convenience or reference. Value of zero doesn"t show total absence of variable being measured. Ex. if temp is 0 degrees, it doesn"t mean there"s no temp outside and it does not stop the temp from going even lower: no conclusions about ratio of one value to another, other common examples include.
