Soft cover. Condición: Good. Sigma Statistics: NCEA Level 3 By David Barton and Claire Laverty. SOFTBACK, ex owners stamp inside, no other annotations, shelf/edge wear 728 pages. Published by Pearson Education New Zealand, 2013. ISBN: 1442556986. Table of Contents The NCEA Level 3 Mathematics and Statistics Achievement Standards for Year 13 -- Foreword to students, parents and teachers -- Investigations -- Puzzles -- CAS calculator applications -- Spreadsheet activities -- Data sets -- Simulations -- 3.8 Time series -- 3.9 Bivariate measurement data -- 3.10 Trigonometric relationships -- 3.11 Statistical experiments -- 3.12 Statistically based reports -- 3.13 Probability concepts -- 3.14 Probability distributions -- Appendices -- Answers -- Index. The parts of the course that have evolved from the current NCEA Level 3 Statistics and Modelling Achievement Standards have been extensively upgraded. The content has been carefully revised in line with best teaching practice, and expanded to respond to changes in the curriculum and assessment. Among the mathematical changes are: new material on probability distributions (Achievement Standard 3.14), focussing on mean and standard deviation being properties of a distribution; coverage of deterministic vs. probabilistic concepts, or true vs. experimental vs. theoretical probability (Achievement Standard 3.13); Among the mathematical changes are: new material on probability distributions (Achievement Standard 3.14), focussing on mean and standard deviation being properties of a distribution; coverage of deterministic vs. probabilistic concepts, or true vs. experimental vs. theoretical probability (Achievement Standard 3.13); new material on risk and relative risk that strengthens the probability section in Achievement Standard 3.13; new simulations. There are still plenty of investigations and puzzles to motivate students.

Hardcover. Condición: New. 1st Edition. Everything we know about the power system, whether for control, or planning, or billing, is the result of a measurement, so the measurements ought to be good. The authors of Measuring the Electric Grid: Mysteries Explained pull no punches in showing how bad today's measurements are, and how to make them better. Misunderstandings about important power system quantities, especially reactive power, apparent power, and phasors, are pervasive. The first four chapters provide foundational information about measurement generally not taught to power engineers. Although power engineers expect their measurements to be "scientific", these chapters explain why some of the most critical power system measurements are distinctly non-scientific and not fit for purpose. In the next four chapters, the most important and most misunderstood measurements are scrutinized more closely. Particular attention is paid to reactive power and to the phasor measurement unit. Although the book discusses serious issues, a little light humor makes for easy reading. Additional topics discussed include: Two fundamentally different kinds of measurement exist; most of the measurements in the power system are of the non-scientific variety Power theories, such as those of Budeanu and Fryze, are shown to be inevitably wrong; measurement theory resolves the mysteries The number of degrees of freedom of a system is an incisive tool for resolving key questions about the nature of measurements Opportunities for further research An introduction to the important topic of measurement uncertainty Measuring the Electric Grid: Mysteries Explained fills a significant knowledge gap for all students in programs of study related to power systems. It is also valuable for practicing engineers working in the manufacturing and utility industries.
