Tham khảo tài liệu 'engineering statistics handbook episode 5 part 3', kỹ thuật - công nghệ, cơ khí - chế tạo máy phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | 3.5.I.4. Analysis of Variance Components of Variance From the above analysis of variance table we can compute the components of variance. Recall that for this data set we have 2 wafers measured at 4 furnace locations for 21 runs. This leads to the following set of equations. 3072.11 4 2 Var Run 2 Var Furnace Location Var Within 571.659 2 Var Furnace Location Var Within 120.893 Var Within Solving these equations yields the following components of variance table. Components of Variance Component Variance Component Percent of Total Sqrt Variance Component Run 312.55694 47.44 17.679 Furnace Location Run 225.38294 34.21 15.013 Within 120.89286 18.35 10.995 NIST SEMATECH HOME TOOLS AIDS 5ÉAỀCH BACK NEXT http www.itl.nist.gov div898 handbook ppc section5 ppc514.htm 2 of 2 5 1 2006 10 18 02 AM 3.5.I.6.

Furnace Case Study 3.5.1.6.Work This Example Yourself View This page allows you to repeat the analysis outlined in the case study Dataplot description on the previous page using Dataplot if you have Macroffor downloaded and installed it. Output from each analysis step below will this Case be displayed in one or more of the Dataplot windows. The four main Study windows are the Output window the Graphics window the Command History window and the Data Sheet window. Across the top of the main windows there are menus for executing Dataplot commands. Across the bottom is a command entry window where commands can be typed in. Data Analysis Steps Results and Conclusions Click on the links below to start Dataplot and run this case study yourself. Each step may use results from previous steps so please be patient. Wait until the software verifies that the current step is complete before clicking on the next step. The links in this column will connect you with more detailed information about each analysis step from the case study .
