Scaling: May be considered as an extension of Measurement. Scaling involves creating a continuum upon which measured objects are located. Scaling describes the procedures of assigning numbers to various degrees of opinion, attitude and other concepts. Scaling is the branch of Measurement that involves the construction of an instrument that associates qualitative constructs with quantitative metric units. A scale is a continuum, consisting of the highest point in terms of some characteristic e.g. preference, fast , etc. And the lowest point along with several intermediate points between these two extreme points. These scale-point positions are so related to each other that when the first point happens to be the highest point, the second point indicates a higher degree in terms of a given characteristic as compared to the third point and the third point indicates a higher degree as compared to the fourth and so on.
The term ‘scaling’ is Applied to the procedures for attempting to determine quantitative measures of subjective abstract concept. Scaling has been defined as a ‘’procedure’’ for the assignment of numbers (or other symbols) to a property of objective in order to impart some of the characteristics of numbers to the properties in questions
A scale may be defined as a continuous spectrum or series of categories and has been defined as any series of items that are arranged progressively according to value or magnitude, into which an item can be placed according to its quantification. The purpose of scaling is to represent usually quantitatively, an item’s, people, or an event’s place in the spectrum.
Scaling has also been defined as a ‘’Procedure for the assignment of numbers or other symbols to a property of objects in order to impact some of the characteristics of numbers to the properties in question.
Scaling is ‘’progressively arranging series of items according to value or magnitude into which an items can be placed according to its quantification’’. Scaling thus constitutes a series of categories through marks. Its purpose is to represent quantitatively item’s (person’s) place in the spectrum.
