| Significance of the Mean. This movie demonstrates the significance of the mean as the value that minimizes the sum of the squared deviations. This movie is also available as a podcast. |
| Normalizing the Variance. This movie provides exploratory motivation for the sample variance formula. Specifically answering the question "Why do we divide the sum of the squared deviations from the mean by n-1?". Excel sheet used in this movie. |
| Making an Excel Worksheet for Showing the Mean as the Least Squared Error Approximation. This movie demonstrates the production of an Excel sheet for visually demonstrating the mean as the value that minimizes the sum of the squared deviations. Excel worksheet produced in the movie. |
| Statistical Rules of Thumb is a website related to a compilation of the a wisdom of a biostatistician. Each of the 99 rules has a brief introduction, a simple statement of the rule, illustrations, theoretical underpinnings, and extensions. |
