Miscellaneous Topics
| Audio Podcast 30 |
What are Confidence Intervals? - Discusses the history, theory and practical use of Jerzy Neyman's confidence intervals. |
| Audio Podcast 28 |
Bayes' Theorem, the Monty Hall Problem and "Deal or No Deal" - Discusses conditional probability, and how it can be used in certain games of chance. This is a primer for more detailed individual research on this important topic. |
| Audio Podcast 27 |
Nonparametric Tolerance Intervals - Discusses the theory and use of nonparametric tolerance intervals, for situations where appropriate probability distributions may not be available. |
| Audio Podcast 26 |
Statistical Tolerance Intervals - Discusses the theory behind tolerance intervals, and their use instead of confidence intervals for the mean response, in certain situations. |
| Audio Podcast 24 |
R-Squared - Discussion about the multiple coefficient of determination (a.k.a. R-squared) as used in designed experiments, regression analysis and elsewhere. |
| Audio Podcast 22 |
Outliers and Boxplots - How potential outliers are identified in John Tukey's Box and Whisker plots. |
| Audio Podcast 20 |
Means vs. Medians - Instances in which the use of the arithmetic mean may lead to misleading conclusions, in comparison with assessing the median of a set of data. |
| Audio Podcast 18 |
Normality Implications - Comments on the robustness of certain statistical procedures to assess Normality. |
| Audio Podcast 17 |
Testing for Normality - Understanding the effect of sample sizes on tests when assessing the validity of probability distributions. |
| Audio Podcast 15 |
Degrees of Freedom in Statistics - Definition and discussion of this statistical term, and the role of degrees of freedom in statistical analyses. |
| Audio Podcast 12 |
Gosset's t-Test - The origin and history behind the famous "Student's" t-Test. |
| Audio Podcast 11 |
Equivalence Tests - Discussion of TOST (two one-sided t-tests) for equivalency assessments, and why "traditional" t-testing is inappropriate here. |
| Audio Podcast 8 |
What is Statistical Power? - Definition of power and a discussion of associated sample size issues. |
| Audio Podcast 7 |
What is a P-Value? - Description of the P-Value and a rule of thumb for remembering how to use it in practice. |
| Audio Podcast 6 |
Statistical vs. Practical Significance - Considers the distinction between practical and statistical significance. Student's one-sample t-test is used for illustration. |
| Audio Podcast 5 |
Anderson-Darling Normality Test - How to understand and interpret the Anderson-Darling normality test, and Normal probability plots in general. |
| Audio Podcast 1 |
(a) How large a sample size do I need to take?, (b) Should all data follow a Normal distribution? |
| |
Some Misconceptions About the Normal Distribution |
| |
Why Divide By n-1? |
