Levels of Measurement. What they are; They are the different ways numbers can be used. NOMINAL LEVEL. Numbers can be used as tags or labels, where the size of the number is arbitrary. Barcodes and social security numbers are two examples. We could use the name of the merchandise or person equally well, but we choose numbers instead.
Interval Level Of Measurement. In interval measurement, the distance between the attributes, or categories, does have meaning. For example, temperature is an interval variable because the distance between 30 and 40 degrees Fahrenheit is the same as the distance between 70 and 80 degrees Fahrenheit.atio Level Of Measurement. Variables that are measured at the ratio level are similar to interval variables, however they have an absolute zero that is meaningful (i.e. no numbers exist below zero). That is, you can construct a meaningful ratio, or fraction, with a ratio variable.
