attribute An attribute is a characteristic of a part or process that can be measured qualitatively. This is often a count of defective units or a list of possible defects.

Attributes are represented in WinSPC by a 'A' inside a blue diamond. Attributes use chart types such as 'p', 'np', 'u', 'c', or a Pareto.
