| 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. An example of an attribute would be the count of the number of units that had a particular visual defect, such as scratches or dents. 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. |
