... Principles of significance tests The general procedure for a significance test is as follows: 1. Set up the null hypothesis and its alternative. 2. Check any assumptions of the test. 3. Find the value of the test statistic. 4. Refer the test statistic to a known distribution which it would follow i ...

Introduction to Probability 1 Probability
... In the 1970’s, there was a game show called Let’s Make a Deal, hosted by Monty Hall and his assistant Carol Merrill. At one stage of the game, a contestant is shown three doors. The contestant knows there is a prize behind one door and that there are goats behind the other two. The contestant picks ...

A Derivation of Bill James` Pythagorean Won

While Bill James used γ = 2 (most likely for simplicity), subsequent analysis of James’ formula has shown a more accurate exponent to be about 1.82. We gen ...
