A review of data handling (types of data, variation, randomness, sampling, frequency distributions, histograms, time series, summary statistics, etc.) is intended to bring all students up to an acceptable level of interaction with data analysis.
Concept of probability. Probability rules. Probability distributions - hypergeometric, binomial, geometric, Poisson, exponential, normal. Probability plots. Confidence intervals. Concept of expectation. Central limit theorem.
Acceptance sampling. Single sampling plans: Acceptable Quality Level, Producer's Risk, Limiting Quality, Consumer's Risk, Operating Characteristic, Rectifying Inspection, Average Outgoing Quality, Average Outgoing Quality Limit, Average Total Inspection. Double sampling plans: Operating Characteristic, Average Sample Number.
Control charts: X bar and range charts for variables, p charts and c charts for attributes, discussion of CUSUM control charts and time weighted charts. Decision rules are introduced and examined. Opportunities are given to decide, use, and select a suitable type of chart, and to construct and use the chart. Average Run Length.
Capability indices (Cp index and Cpk index): their calculation, interpretation, and limitations.
Design of experiments (hypothesis testing): t tests, chi squared test.
Metrology: Identify the importance of measurement, relationship between standards and measurement in a quality process, identification of quality characteristics of a product or service, effect of instrument characteristics on measurement results, GR&R studies.
Six Sigma approaches will be discussed, with examples.
This module will develop a range of graduate attributes, including numeracy skills, problem formulation, problem-solving skills, and the ability to present a clear argument.
- • This module has been reviewed and updated, taking cognisance of the University’s Curriculum Framework principles. Examples of this are found within the module such as active and engaging tutorial activity with contemporary industry examples of modular content, module assessment which reflects industry activities, learning synergies across modules and levels of study and recorded lecture content supporting students to organise their own study time.
