Arrange the following scales of measurement from the simplest to the most evolved.

1.Ordinal

2.Nominal

3.Ratio

4.Interval

A1, 2, 3, 4

B2, 3, 1, 4

C3, 4, 2, 1

D2, 1, 4, 3 ✓ Correct

Correct answer: (D) 2, 1, 4, 3

Explanation

From simplest to most evolved the order is nominal, ordinal, interval and ratio, that is 2, 1, 4, 3.

The nominal scale merely names or classifies and carries the least information.

The ordinal scale adds rank order but not equal intervals between positions.

The interval scale adds equal, meaningful distances yet keeps an arbitrary zero.

The ratio scale adds a true zero, permitting statements about proportions and ratios.

Each higher scale retains the properties of those below it and adds one more.
