B A 360 Lecture Notes - Lecture 12: Control Chart, Standard Deviation, Sampling Distribution
Document Summary
If youre measuring a process, you need to look at the range statistical process and the average control (spc) Variability is part of every process output. Most are due to natural or common causes. " monitoring of production process to detect and eliminate causes sampling technique are used to ! Set upper and limits process outcome of for alterable outcome is m - whn it. Continually monitor process to ensure eliminate assignable causes. Theorem of regardless of sample the distribution of averages drawn from the population will the population , the distribution to follow a normal distribution: mean of the sampling as the population"s mean distribution ci) will be the same. Not of of standard the sampling deviation distribution will equal divided by the square the sample size. E of = rn chart limits control limit ( ucl) = i + zoe.
