What makes a high standard deviation

The key point to remember is variation must be looked at within the context of tolerance. If within control limits and specification limits, your resources are perhaps better spend elsewhere.

If looking at a single factor, I would not consider the magnitude of the variation outside the context of the process capability. If looking at multiple factors in an effort to determine which is more actionable, COV allows you to rank the factors relative to the porportion of variation. Good luck. Coefficient of variation A measure of relative variability, usually calculated only when all values are positive, as in weight, sales, or exam data.

The coefficient of variation expresses the standard deviation of the data as a percentage of the mean. No one has come up with a good rationale for doing anything significantly different. I will be glad to write a Beige Paper supporting my position which I will never submit. And you can count on me not showing up anyway. I learned from the Master But, get Reigle to work on it anyway, it will keep him out of trouble. You will agree that no number is high or low, unless there is a reference. The customer or competition will decide whether a standard deviation value is high or low.

What is high for one could be low for another. How about 75 mV.? For example, Begin typing your search term above and press enter to search.
