They provide concepts, tools and techniques asym help an organization in planning, implementation and evaluation of an effective statistical process control SPC system.
The level of a characteristic may often be taken as an indication of the quality of a material. If so, an estimate of the average value of that characteristic or of the fraction of the observed values that do not conform to a specification for that characteristic becomes a measure of quality with respect to that characteristic. Filled with pages of tables for use with a continuous supply, the documents are our current best-selling sampling standards. Proceed to Checkout Continue Shopping.
This practice will clearly indicate the sample size required to estimate the average value of some property or the fraction of nonconforming items produced by a production process during the time interval covered by the random sample. The practice treats the common situation where the sampling units can be considered to exhibit a single overall source of variability; it does not treat multi-level sources of variability.
