When studying abstract mathematics, one of the best ways to understand the subtleties that are inherent in the abstraction is to keep certain illustrative examples in mind. This allows us to encode the properties of the math we are studying in an easy to understand...

Are there really lies, damned lies and statistics? You don't need to get bogged down in mathematics to answer that. You just need to understand the logic behind probability tests, pvalues and Confidence Intervals.All conventional statistical tests of probability take the form of an...
