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
This is a general introduction to statistics in the form of an interactive online textbook, available for adaptation and reuse under an attribution-only licence. The site describes the book as "designed for the one-semester, introduction to statistics course and is geared toward students majoring in fields other than math or engineering. This text assumes students have been exposed to intermediate algebra, and it focuses on the applications of statistical knowledge rather than the theory behind it." The whole book or individual pages can be downloaded in e-book formats. OpenStax is a project hosted at Rice University and supported by a group of educational charities.

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.
