Statistics for managers class discussion wk12 - Coursework Example Statistical process control is used when we are interested with the effectiveness of a production process. This is because the method uses statistical formulas to predict the suitability of the production process to meet the required standards of consumers. If the number of defectives is higher than stipulated figure, then the process is considered ineffective. If we are more interested with the likelihood of goods produced meeting the threshold of consumer standards, then acceptance sampling is the best method. It uses sampling methods to predict percentage of defective goods. If the extrapolated results do not reflect the minimum specification of defectives, then the whole batch of goods is rejected. It is a faster quality control method. Acceptance sampling involves rejecting or accepting a whole population of goods based on results obtained from a sample. Inspecting a sample is faster than inspecting several samples or a whole population of
