Question

What are the rules to be followed to make accurate measurement with scale?

Answer 1

Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.[1][2] The scope and application of measurement are dependent on the context and discipline. In the natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International vocabulary of metrologypublished by the International Bureau of Weights and Measures.[2] However, in other fields such as statistics as well as the socialand behavioral sciences, measurements can have multiple levels, which would include nominal, ordinal, interval, and ratio scales.[
