Arrange the following levels of measurement in an order from higher to lower level : A. Nominal B.…

According to Stanley Smith Stevens' (1946) typology of measurement scales, the four levels of measurement ordered from highest mathematical precision to lowest are Ratio (C), Interval (D), Ordinal (B), and Nominal (A). Ratio scales possess all properties including a true absolute zero, Interval scales have equal intervals without a true zero, Ordinal scales provide rank order only, and Nominal scales merely classify data into categories. Therefore, the descending sequence from higher to lower level is C-D-B-A.
