Random – Probability, Mathematical Statistics, Stochastic Processes

Random (formerly Virtual Laboratories in Probability and Statistics) is a website devoted to probability, mathematical statistics, and stochastic processes, and is intended for teachers and students of these subjects. The site consists of an integrated set of components that includes expository text, interactive web apps, data sets, biographical sketches, and an object library.

Econometrics & Statistics – MIT Open CourseWare

These are amazing classes posted online by MIT. The books are expensive so I generally use the syllabus outlines and assignment problems to find YouTube videos and chapters from free books on the subjects. For the really good courses I’ll buy the books for the MIT class, when I can afford it 😉

Covariance and Correlation

I think of covariance as a measurement similar to a line’s slope except that instead of using a slope between 2 points we’re using a slope of many points of measurements, which are measurements of distances from means.
