Measurements and Scaling Techniques – Introduction
What is measurement?
Measurement is a process of assigning numbers, or other symbols to the characteristics of an object according to some pre-specified set of rules.
The assignment process must be isomorphic i.e., there must be one-to-one correspondence between the numbers and the characteristics being measured.
The rules for assigning numbers should be standardized and applied uniformly.
Why is it important? It is important because we want to be able to use statistical techniques or analytical techniques to evaluate these numbers.
What is scaling?
It is an extension of measurement. Scaling is the process of assigning numbers to various degrees of opinion, attitude, or other such concepts.
Scaling involves creating a continuum upon which measured objects are located. Example, there is a scale from cold to hot, 1 to 10, etc.
It consists of the highest and the lowest point, as well as intermediate points between the two extremes.
