Summary/Introduction

Measurement means assigning numbers or other symbols to characteristics of objects according to certain pre-specified rules. The rules for assigning numbers should be standardized and applied uniformly.

Rules must not get varied over different objects or at any point in time until completing one successive measurement for all sets of pre-defined objects.

Scaling involves creating a continuum or scale upon which measured objects are located. Let’s consider an attitude scale from 1 to 100. Now, each respondent is assigned a number from 1 to 100, with 1 = ‘extremely unfavorable’, and 100 = ‘extremely favorable’.

Measurement is the actual assignment of a number from 1 to 100 to each respondent. Scaling is the process of placing the respondents on a continuum concerning their attitude toward specific activities or events.
