This data mining type is used for numerical data and time data. Averages can be computed on this kind of data. In databases, sometimes numerical quantities are stored in textual fields.

In the studio, it is possible to declare the data mining type of a textual column (e.g. a column of type VARCHAR) as Interval. In that case, the data should be treated as numerical data and summary statistics should be available.
