| Measure |
Level of measurement or scale of measure is a classification that
describes the nature of information within the values assigned to
variables.
|
| Class | Description |
|---|---|
| CategoricalMeasure |
Categorical data can be stored into groups or categories with the aid of
names or labels.
|
| IntervalScale |
The interval scale allows for the degree of difference between items,
but not the ratio between them.
|
| NominalScale |
Nominal variables take on a limited number of unordered values.
|
| NumericalMeasure |
Numerical data, also called quantitative data.
|
| OrdinalScale |
The ordinal type allows for rank order (1st, 2nd, 3rd, etc.) by which
data can be sorted, but still does not allow for relative degree of
difference between them.
|
| RatioScale |
The ratio scale allows for both difference and ratio of two values.
