Theories of measurement

Theories of measurement explore how we assign numbers to qualities or quantities in a meaningful and consistent way. They examine the principles behind accurately capturing aspects like height, temperature, or intelligence, ensuring that measurements reflect true differences rather than random errors. Different theories, such as classical, ordinal, and ratio, define how scales are constructed and what the numbers represent. Essentially, these theories guide us in developing reliable methods to quantify various attributes, allowing comparisons, assessments, and analyses to be meaningful and scientifically valid.
