The factor defines the shape of the skewness or bell. Usually this is to create some type of surrogate CustomerID or UserID that is a unique number within some range, but is not issued sequentially, and is therefore far less guessable than an IDENTITY value. 16) A pollster uses a computer to generate 500 random numbers, then interviews the voters corresponding to those numbers.
