What are the four measurement scales used in quantitative analysis as described in the chapter?

The four measurement scales used in quantitative analysis are nominal, ordinal, interval, and ratio.

Quantitative analysis employs four measurement scales: nominal, ordinal, interval, and ratio. The nominal scale is the simplest, used for categorization without implying any order or magnitude. The ordinal scale introduces order or ranking but still lacks magnitude and size. The interval scale adds magnitude and equal intervals between values but lacks an absolute zero point. Finally, the ratio scale includes all the features of the interval scale along with an absolute zero, making it the most precise.
