August 12, 2015. This article was originally published at Econometrics Beat: Dave Giles' Blog. And syndicated at StatsBlogs. After taking your first introductory course in statistics you probably agreed wholeheartedly with the following statement:. A statistical distribution is symmetric if and only if it is not skewed.". After all, isn't that how we define "skewness"? In fact, that statement is incorrect. There are distributions which have a skewness coefficient of zero, but are asymmetric. Students are...

For example, the ENCODE data standards document. Suppose you have collected data from an experiment. And want to determine if a second experiment replicates...

Thought you might be interested in an EngageNY lesson plan for statistics. So far no (-2)x(-2) = -4 (based on a quick read), but still kind of weak.
