Attribute Ratings 

To allow you to organize related numeric values within a single named attribute, a numeric attribute can be defined as having up to five ratings, each of which shares the single, common attribute definition. Each rating is a standard Windows checkbox; click on it to toggle each rating on and off. The five ratings are listed in the table below; the default is Nominal.

Rating	Suffix	Description
Nominal	[Nom]	The most commonly applicable default rating when just a single measurement is associated with the attribute.
Minimum	[Min]	The corresponding attribute value is a minimum.
Maximum	[Max]	The corresponding attribute value is a maximum.
Average	[Avg]	The corresponding attribute value is an average.
Typical	[Typ]	The corresponding attribute value is a typical value.

You must specify at least one rating for a numeric attribute.

To distinguish the different ratings for a numeric attribute in attribute lists, MDM appends to the attribute name the rating abbreviation in square brackets (for example, Width [Max]). However, MDM does not append the [Nom] suffix when Nominal is the only rating specified for the attribute.
