An attribute is a (a) or characteristic of an object.
Attributes that have only two states (e.g., 0 and 1) are called (a) attributes.
Attributes with values that can be categorized but not ordered are called (a) attributes.
A numeric attribute that can take only integer values is called a (a) attribute.
A numeric attribute that can take any value within a range is called a (a) attribute.
An attribute where only the presence of a condition is important (e.g., a disease test) is called an (a) binary attribute.
In a (a) scale, the difference between values is meaningful, but there is no true zero.
The four types of measurement scales are nominal, ordinal, interval, and (a) .
