Hypothesis Testing: A Visual Introduction to Statistical Significance Scott Hartshorn
Hypothesis Testing & Statistical SignificanceIf you are looking for a short beginners guide packed with visual examples, this booklet is for you. ****Statistical significance is a way of determining if an outcome occurred by random chance, or did something cause that outcome to be different than the expected baseline. Statistical significance calculations find their way into scientific and engineering tests of all kinds, from medical tests with control group and a testing group, to the analysis of how strong a newly made batch of parts is. Those same calculations are also used in investment decisions. This book goes through all the major types of statistical significance calculations, and works through an example using them, and explains when you would use that specific type instea...
Linear Regression and Correlation: A Beginner's Guide Scott Hartshorn
Linear Regression & CorrelationIf you are looking for a short beginners guide packed with visual examples, this book is for you.Linear Regression is a way of simplifying a group of data into a single equation. For instance, we all know Moore’s law: that the number of transistors on a computer chip doubles every two years. This law was derived by using regression analysis to simplify the progress of dozens of computer manufacturers over the course of decades into a single equation. Correlation is a way of calculating how much two sets of numbers change together. In addition to being part of the regression analysis, correlation is heavily used in investment industries, for instance, to determine if two stocks are likely to change value together or independently.This book goes through...
Probability - a Beginner's Guide to Permutations and Combinations: The Classic Equations, Better Explained Scott Hartshorn
Permutations And Combinations – Better ExplainedThis book gives examples of how to understand using permutations and combinations, which are a central part of many probability problems. The focus of this book is on understanding why the permutation and combination equations are what they are, which ends up making them a lot easier to understand, remember, and expand than simply memorizing the equations.Permutations and combinations is a subject usually makes up a chapter in most statistics text books, but it is a chapter that doesn’t do the subject its proper justice. Most chapters on this subject start and end with memorizing the permutation and combination equations, and miss the deeper understanding of them and also skip over the permutation and combination problems that can’t be solved...
