Ordinal data are data that can be ordered on an ordinal scale in order to rank them.
Natural order can be found in all primitive data type:
Complex data type needs to compute a primitive in order to convey order. For instance:
For instance, ordering data numerically (ranking):
In a temperature scale, there is meaning to the values between the ordinal numbers (i.e. 1/2 degree can be interpreted)
The Ordinal Measurement involves collecting information in which the order is significant and is used to rank order cases. The name of this level is derived from the use of ordinal numbers
