I've just signed up for a introductory course on descriptive statistics offered by UC Berkeley via a www.edx.org, from the website;
EdX is a not-for-profit enterprise of its founding partners Harvard University and the Massachusetts Institute of Technology that features learning designed specifically for interactive study via the web. Based on a long history of collaboration and their shared educational missions, the founders are creating a new online-learning experience with online courses that reflect their disciplinary breadth. Along with offering online courses, the institutions will use edX to research how students learn and how technology can transform learning–both on-campus and worldwide. Anant Agarwal, former Director of MIT's Computer Science and Artificial Intelligence Laboratory, serves as the first president of edX. EdX's goals combine the desire to reach out to students of all ages, means, and nations, and to deliver these teachings from a faculty who reflect the diversity of its audience. EdX is based in Cambridge, Massachusetts and is governed by MIT and Harvard."
It's the first part of a 3 part course that initially goes into regression, standard deviation, scatter diagrams, and my goal here is to be able to pick up some techniques to be able to assess data (ie results from trading) in a scientific way that will lead to meaningful conclusions.
There are quite an eclectic mix of courses offered - you can check them out athttps://www.edx.org/courses.
