PTC MathCAD and Workgroup Manager: Implementation in a Multi-Org System Stakeholder Analysis WorksheetA worksheet that can be used to document potential stakeholder groups, the information or expertise they hold, the role that they can play, their interests or concerns about the HIA The book introduces the most powerful functions and features of the new Prime 3.0 software and teaches how to apply them to create comprehensive calculations for any quantitative subject. Essential PTC Mathcad is perfect for college students and first-time users as well as for experienced Mathcad users who are moving to Prime 3.0. Quickly harness the power of Mathcad to solve simple and complex problems. Learn how to use PTC Mathcad Prime 3.0, one of the world's leading tools for technical computing, in the context of engineering, science, and math applications. In a second Mathcad document, Non-Linear Least-Squares Regression, Young andĮssential PTC Mathcad Prime 3.0 a guide for new and current users Alternatively, instructors may select sections of the document suited to the skill level of their students and the laboratory tasks at hand. Any linear or linearizable data set would be appropriate for use with this Mathcad worksheet.
It would be worthwhile for students to spend one or two laboratory periods learning to use the concepts presented and then to apply them to experimental data they have collected for themselves. The worksheet is accompanied by a set of data for students to use to practice the techniques presented. Although the statistical methods presented in this worksheet are generally accessible to average physical chemistry students, an instructor would be needed to explain the finer points of the matrix methods used in some sections of the worksheet. There is full documentation of the various steps used throughout the exposition of the statistical concepts. The document concludes with a discussion of and practice with adding a quadratic term to create a polynomial fit to a set of data and how to determine if the quadratic term is statistically significant. Examination of the residuals of the fit leads students to explore the possibility of rejecting points in a set of data. Students are next given the opportunity to examine the confidence level for the fit through the Student's t-test. The document shows how to determine the standard deviation for the slope, the intercept, and the standard deviation of the overall fit.
Young and Andrzej Wierzbicki demonstrate various implicit and explicit methods for determining the slope and intercept of the regression line for experimental data. In Linear Least-Squares Regression, Sidney H. With this column we add three peer-reviewed and tested Mathcad documents to the JCE site. Mathcad in the Chemistry Curriculum Symbolic Software in the Chemistry CurriculumĬollection of peer-reviewed documents is developing through this column at the JCE Internet Web site, McadInChem/index.html.
