Probability and statistics

Summary

In any discussion of system reliability or quality control, the concept of probability plays a vital part. It is also a vital issue in the consideration of statistics when errors have to be considered in experimental measurements, all measurements being subject to some degree of uncertainty. For example, in the control of manufactured items (statistical process control SPC) control is exercised of measured variables against go/no-go criteria, the attribute, to avoid incurring scrap or reworking costs. This chapter is an introductory consideration of the principles of probability and statistics allied to such engineering issues.
