it takes the one value with probability 1, then there is no surprise. Think 1-sided dice, or a two-headed coin (both sides are ‘head’). Every draw results in the same value; so your guess is always going to be correct, zero surprise. In that case the entropy of that random vari...
In this section, I’m going to show you the formal definition of expected value and how to actually calculate it. I’m also going to give you some intuition about it by showing its relationship to the arithmetic mean and the law of large numbers. As always, I’m going to give you a...
ValueVariable, depending on the sample.Fixed. The most common statistic is themean. It represents the average of a dataset. Other common statistics include the median and the mode. The median is the middle value in a sorted dataset, while the mode refers to the most commonly occurring value...
Range of Motion, ArticularStatistics as TopicIn the 1920s, Ronald Fisher developed the theory behind the p value and Jerzy Neyman and Egon Pearson developed the theory of hypothesis testing. These distinct theories have provided researchers important quantitative tools to confirm or refute their ...
To make good predictions, to make reasonable recommendations, we need to take this uncertainty into account.In the past, most related research results were based on using traditional techniques from probability and statistics, such as p-value-based hypothesis testing and the use of normal ...

The phenomenon of regression toward the mean is notoriously liable to be overlooked or misunderstood; regression fallacies are easy to commit. But even whe
