SPC-PC IV offers the following charts for attribute data:
NP, C, P, and
U charts based on data entered as counts or
percentages.
Display as fraction, percentage, parts
per million, or user-defined labels
Control limits based on constant, varying
or average subgroup size.
Perform short run
analysis.
Pareto DiagramTo determine
which of several classifications have the highest count or cost associated
with them, a Pareto Diagram prioritizes competing or conflicting problems
so that resources are allocated to the most significant
areas.
Run Charts For plotting individual data values without statistical control limits, Run Charts automatically employ Western Electric Run Test 2, 3, and 4 as an option to recognize trends.
