Appropriate statistics for ordinal level data : Should we ...
The four levels of measurement that were proposed by Stevens are nominal, ordinal, interval, and ratio. At the nominal level the variables are categorical and there is no order.
1 Measurement Scales
Traditionally, statisticians talk of four types of measurement scales: (1) nominal , (2) ordinal , (3) interval , and (4) ratio . 1.1.1 Nominal Scales The word nominal is derived from nomen , the Latin word for name.
