Comparative Scaling types:

Rank order comparison- The subject is given various items and has to rank them in a specified order. For Example -Ten fear items related to fear of heights are given to the person, and he has to rate it from most to least fearful.

Constant sum scaling- In this, certain number of points are allocated to some categories or areas. For Example - In a career aptitude test, various areas such as mechanical, clerical aptitude are presented with and for each the person has to allot points from a total given number of points
