Answer 1

A measurement scale is a system for assigning values or numbers to a particular attribute or characteristic being measured.

Key Points

Nominal scale is a measurement scale used for data that can be placed into distinct categories or groups, where the values assigned are arbitrary and there is no inherent order or numerical relationship between the categories.
It is the lowest level of measurement in which data is classified into mutually exclusive categories.
Values assigned to nominal scale of measurement are arbitrary which means that they do not have any numerical value or meaning beyond simply identifying a category or group.
In other words, nominal scales are used to categorize data into distinct groups or labels, but there is no inherent order or numerical relationship between the categories.
The categories are usually represented by numbers or symbols, but these values are purely arbitrary and could be replaced by any other set of values without changing the meaning or structure of the data.
For example, assigning the values of 1, 2, 3 to different colors like Red, Green, Blue in a survey questionnaire is arbitrary and the same data could be represented by assigning different values like 3, 7, 9 to the same colors.
