It begins with a brief overview of measurement principles supplemented with many examples to provide necessary background to the reader. In 1801, Gauss developed the method of least squares in calculating the orbital component of the motion of celestial bodies with high accuracy. In other words, properties like weight, height, etc., can be measured directly with some standard unit of measurement, but it is not that easy to measure properties like motivation to succeed, ability to stand stress and the like. The social construction of measurement is frequently encountered in social science disciplines. With respect to market research, the common ratio scale examples are price, number of customers, competitors, etc. /Type /Page

Nominal scale: Nominal scale is simply a system of assigning number symbols to events in order to label them. %����
Examples include income in dollars, length or distance in meters or feet, age, and duration in seconds or hours.

Unlike with the nominal and ordinal scales, you can make relative distance measurements among objects using the interval scale. Measurement is the evaluation or estimation of degree, extent, dimension, or capacity in relation to certain standards (i.e., units of measurement). The ethnicity measure for Hispanic doubled the total number of the race/ethnicity categories to 126. Examples of ratio measurements are speed, weight, velocity and area. The categories of assignment in most situations are defined arbitrarily, for instance, numbers assigned to individual marital status: single = 1, married = 2, separated = 3, divorced = 4, and so on, or to religious preference: Christian = 1, Jewish = 2, Muslim = 3, Buddhist = 4, and so on.
