4434Exercises in Statistical Inference with detailed solutions
http://www.merlot.org/merlot/viewMaterial.htm?id=1016990
'Statistical inference is a process of drawing general conclusions from data in a specific sample. Typical inferential problems are: Does alternative A give higher return than alternative B? Is drug A more effective than drug B? In both cases solutions are based on observations in a single sample.To solve inferential problems one has to deal with the problems: (i) How to find the best estimate of an unknown quantity, (ii) How to find an interval that covers the true unknown value and (iii) How to test hypothesis about the value of an unknown quantity. The treatment of these issues can be found in a large amount of statistical textbooks. The present book differs from the latter since it focuses on problem solving and only a minimum of the theory needed is presented.'Tue, 21 Apr 2015 14:21:59 -0700Introduction to Probability - Probability Examples c-1

'Our emphasis in this text is on four main concepts:thinking statisticallyincorporating technologyworking collaborativelywriting thoughtfullyThese concepts are integral to our course. Students learn the best by actively participating, not by just watching and listening. Teaching should be highly interactive. Students need to be thoroughly engaged in the learning process in order to make sense of statistical concepts. Collaborative Statistics provides techniques for students to write across the curriculum, to collaborate with their peers, to think statistically, and to incorporate technology.This book takes students step by step. The text is interactive. Therefore, students can immediately apply what they read. Once students have completed the process of problem solving, they can tackle interesting and challenging problems relevant to today’s world. The problems require the students to apply their newly found skills. In addition, technology (TI-83 graphing calculators are highlighted) is incorporated throughout the text and the problems, as well as in the special group activities and projects. The book also contains labs that use real data and practices that lead students step by step through the problem solving process.At De Anza, along with hundreds of other colleges across the country, the college audience involves a large number of ESL students as well as students from many disciplines. The ESL students, as well as the non-ESL students, have been especially appreciative of this text. They find it extremely readable and understandable. Collaborative Statistics has been used in classes that range from 20 to 120 students, and in regular, honor, and distance learning classes.'Tue, 4 Nov 2014 13:40:49 -0800Probability and Statistics

'This module consists of three units:Unit 1: Descriptive Statistics and Probability DistributionsDescriptive statistics in unit one is developed either as an extension of secondary mathematics or as an introduction to first time learners of statistics. It introduces the measures of dispersion in statistics. The unit also introduces the concept of probability and the theoretical treatment of probability.Unit 2: Random variables and Test DistributionsThis unit requires Unit 1 as a prerequisite. It develops from the moment and moment generating functions, Markov and Chebychev inequalities, special univariate distributions, bivariate probability distributions and analyses conditional probabilities. The unit gives insights into the analysis of correlation coefficients and distribution functions of random variables such as the Chi-square, t and F.Unit 3: Probability TheoryThis unit builds up from unit 2. It analyses probability using indicator functions. It introduces Bonferoni inequality random vectors,, generating functions, characteristic functions and statistical independence random samples. It develops further the concepts of functions of several random variables and independence of X and S2 in normal samples order statistics. The unit summarises with the treatment of convergence and limit theorems.'Tue, 4 Nov 2014 13:04:04 -0800Online Statistics Education

'This is a collaborative effort led by David Lane of Rice University. The core material is an interactive textbook that is best used over the Internet to take advantage of the embedded questions created in JavaScript. The PDF version that can be downloaded simply shows the answers in a different font following the questions.An attractive feature of Online Statistics is the suite of case studies making use of the actual data from published studies in the scientific literature and popular media. The data sets for the case studies are provided as Excel files. The website also provides some computational tools running in the browser for the statistical calculations needed for the analysis of the case studies, although instructors may prefer to use free software such as R or software already available at their institutions.Also part of the course is a set of 31 simulations illustrating key concepts such as the meaning of a 95% confidence interval. Some are written in JavaScript and run without difficulty, but others are written in Java and may present a problem because of the security concerns surrounding Java applets running in browsers.'Mon, 3 Nov 2014 18:53:33 -0800Introduction to Probability

http://www.merlot.org/merlot/viewMaterial.htm?id=905334
This web site contains notes and materials for a course on statistical forecasting that has been taught at the Fuqua School of Business, Duke University, for over 30 years. It covers basic techniques of data analysis as well as linear regression and time series forecasting. It emphasizes practical, hands-on computer modeling and is intended to serve as a complement rather than a substitute for traditional courses and reference materials on statistics. The material on regression is illustrated with output from RegressIt, a recently-developed free Excel add-in whose procedures for descriptive data analysis and ordinary linear regression offer high-quality output and support for good modeling practices. (http://regressit.com) This content on this site should be useful as self-instruction and reference material for students and practitioners who use regression and time series forecasting methods, as well as anyone who uses Excel-based tools for statistical analysis.Sat, 1 Nov 2014 13:42:30 -0700Introductory Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=880392
'This book is meant to be a textbook for a standard one-semester introductory statistics course for general education students.Over time the core content of this course has developed into a well-defined body of material that is substantial for a one-semester course. The authors believe that the students in this course are best served by a focus on the core material and not by an exposure to a plethora of peripheral topics. Therefore in writing this book we have sought to present material that comprises fully a central body of knowledge that is defined according to convention, realistic expectation with respect to course duration and students’ maturity level, and our professional judgment and experience.'Wed, 23 Jul 2014 10:41:32 -0700CK-12 Probability and Statistics - Advanced (Second Edition), Volume 1 Of 2
