5-832: École nationale de la statistique et de l'analyse de l'information ( ENSAI ) a French engineering College created in 1994. The school is the only engineering school entirely dedicated to the jobs of statistical engineering and information processing. Located in Rennes since 1996, the ENSAI is a public higher education institution. The school is a member of the Conférence des Grandes Écoles (CGE). Engineering statistics Engineering statistics combines engineering and statistics using scientific methods for analyzing data. Engineering statistics involves data concerning manufacturing processes such as: component dimensions, tolerances , type of material, and fabrication process control. There are many methods used in engineering analysis and they are often displayed as histograms to give
10-430: A British mathematician named Charles Babbage designed the idea of an automatic computer which inspired developers at Harvard University and IBM to design the first mechanical automatic-sequence-controlled calculator called MARK I . The integration of computers and calculators into the industry brought about a more efficient means of analyzing data and the beginning of engineering statistics. A factorial experiment
15-400: A different result when together than either would on its own. Six Sigma is a set of techniques to improve the reliability of a manufacturing process. Ideally, all products will have the exact same specifications equivalent to what was desired, but countless imperfections of real-world manufacturing makes this impossible. The as-built specifications of a product are assumed to be centered around
20-524: A visual of the data as opposed to being just numerical. Examples of methods are: Engineering statistics dates back to 1000 B.C. when the Abacus was developed as means to calculate numerical data. In the 1600s, the development of information processing to systematically analyze and process data began. In 1654, the Slide Rule technique was developed by Robert Bissaker for advanced data calculations. In 1833,
25-417: Is one where, contrary to the standard experimental philosophy of changing only one independent variable and holding everything else constant, multiple independent variables are tested at the same time. With this design, statistical engineers can see both the direct effects of one independent variable ( main effect ), as well as potential interaction effects that arise when multiple independent variables provide
