Cumulative conforming count chart

WebThe cumulative conformance count (CCC) chart has been used for monitoring processes with very low fraction of nonconforming items. Typically, the items produced from the process were examined using 100% inspection for generating the CCC chart. However, this would be costly when taking the inspection cost and time into consideration and thus limit … WebThe cumulative frequencyis the total of the absolute frequencies of all events at or below a certain point in an ordered list of events. [1]: 17–19 The relative frequency(or empirical probability) of an event is the absolute frequency normalizedby the total number of events:
