The list of possible values may be fixed (also called finite); or it may go from 0, 1, 2, on to infinity (making it countably infinite).For example, the number of heads in 100 coin flips takes on values from 0 through 100 (finite case), but the number of flips needed to get 100 heads takes on values from 100 (the fastest scenario) on up to infinity (if you never get to that 100th heads). Single number: Nominal Variable Classification Based on Numeric Property Nominal variables are sometimes numeric but do not possess numerical characteristics. The only difference is that arithmetic operations cannot be performed on the values taken by categorical data.

Ordinal numbers tell us an item's position in a list, for example: first, second, third, fourth, etc. She is the author of Statistics For Dummies, Statistics II For Dummies, Statistics Workbook For Dummies, and Probability For Dummies.
