Identify correct sequence of Steven’s four levels of measurement scales : (i) Ordinal (ii) Interval (iii) Nominal (iv) Ratio Codes :
(iii) (i) (ii) (iv)
The four levels of measurement were proposed by psychologist S.S. (Stanley Smith) Stevens in his 1946 paper "On the Theory of Scales of Measurement" in Science. Each level adds a property to the one before it.
(iii) Nominal – lowest level; numbers or labels only name categories (e.g. gender, subject of a book). Only counting and the mode are possible.
(i) Ordinal – categories can be ranked in order (e.g. user satisfaction: low, medium, high), but intervals between ranks are not equal.
(ii) Interval – equal intervals between values but no true zero (e.g. temperature in °C).
(iv) Ratio – highest level; equal intervals plus an absolute zero, so ratios are meaningful (e.g. number of books issued, age).
So the sequence is Nominal → Ordinal → Interval → Ratio, i.e. (iii) (i) (ii) (iv).
Hence, the answer is (iii) (i) (ii) (iv).
