Not specifically aimed at economists, but this is an overview of errors and fallacies in the use of statistics for scientific inference. It presumes no prior knowledge of statistics. Base rate fallacies, underpowered tests, misinterpretation of significance, and regression to the mean are among the topics.
Online Text and Notes in Statistics for Economists
School of Data is an extensive site aiming "to empower civil society organizations, journalists and citizens with the skills they need to use data effectively." The site includes many textual "courses" explaining topics such as Exploring and Understanding Data, Common Misconceptions, Data Cleaning, or Data Journalism. There are also "recipes" explaining how to do tasks with specific tools. Often the tools are simple and freely available, such as Google Spreadsheets. The content is freely reusable and makes copious use of graphs and illustrations.
These case studies in data search, management and economic interpretation are aimed at first-time students of economics. They are downloadable in Word format with embedded links, to adapt, print and/or put in a virtual learning environment. They were produced by Dean Garratt and Stephen Heasell, Nottingham Trent University as part of an Economics Network project. They cover topics such as economic growth, house prices, household debt, consumption spending and government spending.
Part of the MIT OpenCourseWare website, this page provides access to all the materials for Introduction to Statistical Method in Economics, as taught by Herman Bennett in spring 2006. The site includes a course syllabus, details of readings, lecture notes, assignments, exams and links to related Internet resources. Users can access the course online or download the whole thing as a .zip file.
This is an open online course, available freely to independent learners but with a fee for students. The course makes much use of online text, diagrams and interactive assignments. It is comprised of four units: Exploratory Data Analysis, Producing Data, Probability and Inference. These are subdivided into a total of twelve modules and more than two hundred "pages" of material.
This is an open online course, available freely to independent learners but with a fee for students who want feedback from an instructor. The course makes much use of online text, diagrams and interactive assignments. It is comprised of four units: Exploratory Data Analysis, Producing Data, Probability and Inference. These are subdivided into a total of twelve modules and more than two hundred "pages" of material. It is similar to the companion course on Statistical Reasoning, but with a more classical treatment of probability.
These free course materials require a login, either via Google, Facebook or a Udacity account. They cover "Visualizing relationships in data", "Probability", "Estimation", "Outliers and Normal Distribution", "Inference", and "Regression". The "classroom" link takes you to a large number of short YouTube videos each explaining a different step. The "Materials" link takes you to detailed, line by line transcripts which can be downloaded as PDFs. These include some formative questions. As with other MOOCs, there is a forum for learners to discuss questions arising from the material.
These free course materials require a login, either via Google, Facebook or a Udacity account. The course is organised in six modules and aims to cover the basics of statistical research using everyday examples. The "Materials" button links to downloadable videos, an index of concepts and a booklet of notes. "Classroom" leads to a series of short videos with interactive features. As with other MOOCs, there is a forum where learners can discuss questions.
This site has worksheets, short case-studies and other materials to promote data-handling skills and statistical literacy. Tips are given on how to locate and verify data, how to meaningfully test and present it and how to detect misrepresentations and fallacies. There is a glossary and illustrations of how businesses make use of data. The site is part of the Biz/ed service and uses data from MIMAS.
An introductory tutorial on the use of Excel with time-series data, divided into four pages with screenshots, part of the TimeWeb part of the Biz/ed service. It aims to "develop your data-handling skills; building your confidence by using a sample set of data from (UK) National Statistics".
This course webpage supports an introductory module on quantitative economics as taught by Fowad Murtaza and Domenico Tabasso at the University of Essex in 2009/10. It introduces students to the methods of quantitative economics, i.e. to how data are used in economics. Beginning from an elementary level (assuming no background in statistics), the course shows how economic data can be described and analysed. The elements of probability and random variables are introduced in the context of economic applications. The probability theory enables an introduction to elementary statistical inference: parameter estimation, confidence intervals and hypothesis tests. With these foundations, students are then introduced to the linear regression model that forms a starting point for econometrics. It includes a course outline / handbook, lecture presentations, lecture notes, coursework assignments, problem sets with solutions and statistical data.
StatNotes : Topics in Multivariate Analysis is a textbook written by G. David Garson of North Carolina State University for a public administration course. This online version contains articles on a range of statistical topics ranging from Association to Weighted Least Squares (WLS) Regression. Articles typically contain an overview, an explanation of key concepts and terms, assumptions, frequently asked questions and a bibliography. Some of the articles also contain SPSS data / outputs with commentary.
Seeing Statistics is an online text book teaching statistics using the Internet. It requires registration before full use, but a sample tour is available for free. Text includes glossary and calculator. The site uses a succession of pop-up boxes for navigation which may be confusing to users or not appear if pop-ups are disabled by your Internet browser.
The Chance project aims to help teachers and lecturers teach a basic understanding of probability and statistics. This page hosts examples of probabilistic and statistical reasoning, with links to related activities, simulations, videos, and data sets. Related links are also included.
This is a free online textbook on probability and statistics, making a lot of use of algebra. It starts with revision of mathematical tools including differentiation, has sections on foundations of probability and moves to more advanced topics such as Markov's inequality, probability mass and density, asymptotic theory and mathematical foundations of statistics. The site comes with a glossary.
An index of learning materials that are based on a specially selected data set from the 1991 and 2001 UK Census. Each of the 14 modules has slides, detailed notes and statistical exercises involving the data sets.
This course page supports an MBA course at the University of Portland, as taught by Todd Easton in 2008. It covers Statistical and Quantitative Analysis and presents tools for descriptive statistics and details their effective use. The page features a range of course materials - syllabus, past exams, Java applets etc. but perhaps most importantly it includes a booklet on Excel skills, with accompanying data.
